Fair thaughts, but if you only nerf one of the OP combos you only make this one unatractive and the players go to other OP combos.
Only one example:
- Infiltrator/Berserker with Sniperist perk, double stealth bonus and adrenalin rush. This combo deals even more damage per turn as Sniper/Heavy with rageburst (x2 stealth x4 AR = x8 damage compared to x5 damage from RB) and can shred almost any armor with the first shot by using berserkers armorbrake.
You can even top this if you have the trooper perk by using assaultrifles and here explicitly the daimos because of its high accuracy, higher base damage per burst than sniper rifles and then 6 times armorbreak for the first shot. Make the math and your RB combo is simply weak compared to that.
And there are some other combos that can do also a big amount of damage per turn.
Short:
Closing only one hole doesn’t help much but yes, maybe we should at least start with the obvious ones.
