I'm leveling pretty fast but am currently dissapointed with weapon upgrades as Raven.
I have a few tips for spending skill points that I would like to share with you (as Raven, not sure if skills are different for Valor & SVER)
1st, I believe every soldier should have the first medkit with basic resurrection. Although it only raises them to 50% health (and usually you die right away because your health is so low) it's vital that your squad doesn't have to run back from spawn if possible.
2nd, Athleticism is very important; put aside your thirst for kills and concentrate on your ability to stay alive and you will get more points (I 2x my score by doing so). It costs 5 skill points for only 20 more hitpoints but considering you have to purchase either "Grendade resistance' or "Gas resistance" it makes a huge difference. Getting sniped while parachuting in..you can take that single shot now. Dieing by a single grenade..you can survive now. I can't tell you how many times my health has been down to 6-18, I would have been dead without the extra grenade protection or extra health.
3rd, if going heavy on Raven don't bother getting the new machine gun; seriously it has lower specs then the orginal unless equiped with scope and handle to make it -even. Only difference is you get a little bit more stopping power but the weapon weighs more and therefore you get less bang for your buck.
4th, mine as well buy mines! Easy EASY points, set these mines correctly at your fargo point and watch your points and kills rocket up. It's the easist points you can get as you are out of harms way and since you place these near your fargo location you get double the points. This is also a good indication that someone or a group is near that objective. If you see that you killed someone using those mines be prepared to hear the siren go off that your objective is being taken. These are also good to place in locations to help keep you safe. If your in a location that requires stairs to get to you placing one of these charges will protect and warn you.
5th, I mentioned athleticsm before and one of the nice things about obtaining the health bonus is that you also sunk some points into your recovery time and sprint time. This will allow you to wear heavier armor if needed without feeling like a tank. Running longer, with heavier armor, increased health and grenade resistance means you can put yourself at a higher risk..outlast many opponents and revive team mates while taking fire.
6th, Gas isn't always a good thing to throw! Please warn your team mates before throwing gas at an objective. Nothing is worse then having a clear objective free of your opponent and trying to secure the objective before you die from Gas that was thrown without need. Having a lot of health, armor and everything else doesn't stop you from becoming weak quickly because your sucking gas. Don't make your opponents job easier by weaking your team mates.
7th, Remember the recharge time needed for medics. Don't get all pissy if a medic revives someone lying next to you but doesn't revive you right away. Since it takes a minimum of 5 seconds to charge up the medkit again that is 5 seconds an enemy could be trying to take out the medic or the medic could be taking out someone who is about to kill another team mate. if you are a medic that has been killed and is now being revived, the first thing you should do is swap to your medkit and spam a dust cloud. You might rez someone or refill someones HP, other people besides you play the game and they might need your help.
8th, Snipers are not useless...sometimes! If your team is ahead of you securing an objective dont camp back at spawn! If your team mates keep dying by the same sniper ask them where they are, you can get a kill and save your team mates at the same time! Your focus as a sniper should be support, that is what a sniper does. You don't hear about snipers being rambos because that is not what they are trained for. 1 shot, 1 kill. You protect your team mates from other snipers and threats they cannot see, if your team is 100 yards in front of you what good are you to them with a enemy sniper 100 yards ahead of them!
9th, Learn how to mute your mic people. I don't care what your mom is picking you up for dinner at McDonalds. I don't care that your girlfriend is complaining that you where supposed to leave an hour ago but your still "Playing that damn game". I don't care that your buddy called and asked what you are doing to your reply "playing some shitty game, these people suck". What I do care about is not being able to hear anyone else over your rudeness or your mouth breathing driving me crazy. Hearing someone who sounds like a grown man complain that his mom messed up his cheeseburger order is funny and not for the reasons you where hoping!
Finally 10, thank your team when you win. You don't have to go all beauty pangent on them but a quick "thanks guys, good work" or "we kicked their asses" sticks with those you play with. It really shows a fatal flaw in this game because unless those you just played with are on your friends list chances are playing with them is going to be sporatic. I don't know about the rest of you but I remember the "good" players and the "bad" players and join groups accordinaly.
Another suggestion.. Join a clan, the game is more fun when you are playing with a group of people consistantly. I have a member in my clan who is a beast..rambo.. with a high amount of kills but he also revives people. I have other members who don't do as well but what they do is help the team and since they are in a clan they communicate all the time. If your not going to join a clan, try to play with one as much as possible. The game is so much different when your in a squad that has 2-3-6 clan mates in it.
