Lordus look...If you want to call this anything, than this is a hidden SG buff. Not a hidden BG nerf, because it has an effect on every single action in the game. Even on snipers. Throwing grenades. Throwing knives. Switching weapons. Healing. etc etc etc. Im standing in my base making rotgut, wood is in one of my hands, fruit is in the other. And i have constant zero AP. Its just not right. If anyone isnt thinking globaly, its you because you think this is the only advantage SG has over BG. Game needs balance sure. But you just cannot take BUGS into account when you try to balance. Bugs-need-fixing. Simple as that. If the bug is gone, and you have an intended enviroment, you can start testing, giving feedback, devs balance.
Fast ending fight are indeed a problem, i agree on that, but AP regen isnt the problem. It would actually be better to have 0 AP out of combat in RT, and when somebody initiates an attack and combat opens up, AP would start to generate. This way, no minigunner could burst 3 times in a row. They would have the first attack however, because bursting costs less AP. But thats ok right? Low AP action beeing faster then high AP action. This system would be a kind of "RT sequence".
The other and main problem however is that weapons are powerfull, players have low hp. No RPG out there features death in 1-3 hits. Sure this is realistic, but has a serious negative impact on gameplay. Its just not satisfying to kill with no effort, and its even worse ofc if you die with 0 chance to defend yourself.
How this could be improved? Players should have 2x hp as default. In TB, the health would be halved during combat. But this is offtopic
