Onehit/oneshot without some charge time must not be allowed. All other.. just need some balancing. TTK is ok if some tactic decisions available. For example if a player is under fire or in melee he must have some time for cover or shoot/hit back, not dying immediately without any chance.
it will, but we might also have to suffer without it. And solution to powerfist will be tone down powerfist, not melee itself, what was already done, actually. Current melee v melee is best, 2 mistakes are exactly as long as it must be, ranged v ranged can surely be fun in a lot of TTK ranges, but what makes me sad is melee v ranged state, when melee is completely trumped. The only way to actually keep up, especially in multi-directional engagements is abusing the hell out of infinite iframes JA have, which is not normal.
Not that simple. You tone it down, it becomes useless vs armor as there are no damage modifiers, just raw hp. Overall, TTK for anything that isn't PF won't change, so don't panic.
I don't want to go to deep into detail or analyse anything, I just want to say I have found it fun to play with the current Plasmagun rapidfire. (In a Plasmagun vs Plasmagun encounter). The weapon feels right to me. (and I know it's OP, but if it even feels good to play against others who use the same, maybe just the Bolters TTK should be adjusted to this level.
It's also hard to judge ranged TTK until we've got the weapon mods because accuracy is crap right now! When the weapons are more accurate the ranged TTK will surely reduce.
Plasma should be "rare" and very effective. You can balance this with some kind of weapon costs, and/or slow down plasma rate of fire. Slowing down the rapid fire plasma rate will create a situation where missed shots are punishing for the shooter. This way you still have plasma very strong and effective but more balanced if your aren't as easily able to achieve efficiency aka high accuracy with it.
Plasma should have More risk when overheating, like you take some damage to your health when you overheat after some auto-shots. That way you make each shot count, and don't abuse of it. The plasma is good, Melta is balance, Bolter needs more precision.
