Yeah, I hope they keep R2 running, and, if possible, have a separate team to extend the co-op after R3 is out.
R2 competitive MP modes are not that different from RFOM. The major differences are weapon wheel + secondary fire, and weapon spawns. I have a feeling there is a middle ground there. But naturally, we need to play for real to appreciate the differences.
R2 SP is different from RFOM SP. I personally prefer RFOM because it's better paced, and more flexible (No "Hey, you should use this weapon next" hints in-game). RFOM SP also supports co-op, which many should be happy.
R2 competitive was completely dumbed down in terms of how players would organize themselves and tackle objectives, you're basically herded from one objective to another, there was very little creativity involved compared to RFOM where people developed strategies in terms of how to take down nodes in breach and assault (choosing which nodes to capture to get a forward spawn and figuring out where to use the auger to punch through walls at the base node), or how to attack and hold nodes in meltdown, all of it was completely gone in R2. It wasn't just the weapon wheel.
