They said in a lot of the videos they are still tweaking the damages. I think some of it is a bit over-powered, but a lot of the guys on YouTube who flew out to play the new map and/or play the CTE servers are saying DICE is still balancing things. Take that with a grain of salt I guess because DICE always seems to make things too strong or way too nerfed after that. Not sure how much I want hover tanks & railguns either. I say just make separate games or a map or two like that. I think Premium is the best value out there, but sometimes I feel like each map pack is so segmented in what it contains. I'd rather have "straight across the board" type of updates.
Regardless, they are doing a HUGE console patch in late September that should make the game a lot better. PC is getting it too.
