Given the new state of ground there are going to have to be some fundamental re-discussion. Beginning with the evaluation of gear, moving on the evaluation of BO abilities. There are some points in the new ground system that need to be look at carefully. I am beginning to think moving away from Cap as the best value on shields towards looking at something else being more important. I agree with Weapons Malfunction as being very valuable but hand in hand with that any status effects that CC targets; pacification, stun and the like all seem likely to be come the most useful abilities available. With the arrival of S4, Overwatch also might need another long discussion.
Oh I think it won't be too too bad, though if they don't fix Ogen New Infected won't be very exciting. They upped Healing a little. Full auto weapons are awesome. There will be q_q but there always are. Doffs to Come!
