simple talent tree changes could fix a lot of problems - at least in my opinion. add a talent or just even change sticky grenade to -> slows taget for 50% 4 - 5 sec after explosion; on demand slow with 15 sec cd in addition change cover fire to something like -> 5 sec after using a full auto, charakter is imune to interrupts; would also fix brainless gravround spamming at last, change adrenaline rush to something like -> regain 50% (up from 15%) of health over 5 sec (down from 10) on 2min cd problems fixed and, at least in my opinion, no gamebreaking changes to merc / commando class
