it's only the multiplayer...
I'm only worried about the Hamer of Dawn (satellite laser) might be cheap but it looks like it takes a long time to target an area so it probably won't be something you use without good, cooperating team mates.
It's optional. If you don't want it in Multiplayer you don't have to have it. Personally I love to have that one overpowered weapon because it adds tension as to which team can get it first and if the other team has it you have to work together inorder to take him out.
