Hehe, it's only the first stage. There's a lot of stuff that still has to be added to Ops, and obviously a few minor corrections.
RUb 1.43 in general though will be a bit of a transition I think (well, at least from my perspective of having re-worked almost the whole survivability system for it). Which is why I hope there's feedback on it.
I'll be sure to post some 'insider' RUb 1.43 survival tips the day it's out
