There are a lot of major changes coming in this upcoming update with even more suggestions being hurled at oki off cool down. Instead of dumping them all at the same time it might be more useful to implement them one at a time.
The last 3 updates have lead to major issues in game (ie invincible mines, the week where official servers became teleport servers, artificial squad point inflation, repair xp being giga inflated, silent RPGs, in game net code and hit reg deteriorating massively compared to what it was the first 2 months etc)
This upcoming update is already filled with loads of major changes instead of trying to last second force even more content into it, deploy it as is and see if the game can still function at scale and see how these changes impact the game. Constant minor updates would be far more satisfying rather than these 4-6 week major updates we have been getting.
Along with this by spacing the updates out you can see how each individual update effects the game. In regards to this particular update unit collision, further class reworks and other major changes shouldn't be added until you see how the overall gameplay loop is effected by the massive healing change and the addition of the battlefield spotting system. All of this should make it much easier to identify and fix bugs as well rather than having to go in and fix one problem and creating 15 new ones as a result.
Tl;dr: release smaller updates at a higher frequency.
My greatest fear is that this update will not be play tested before f2p weekend and 50k players will wind up playing a broken buggy mess leaving a foul taste in their mouth for what is a marvelous game.
