Xp should accurately reflect the value of the in-game action, if it doesn’t then xp becomes meaningless, like in Brink, that ruins any sense of achievement which in turn completely destroys anything an F2P has going for.
My concern is how that will be achieved. Already I feel a little cheap killing people as the assault class and currently there’s little reason to bring one along - not when a medic or engie will be that much more valuable. So what happens now, buff his health even more, give even bigger guns?
Well exactly those two solution are what would cheapen it more yeah. That’s why I believe we should step away from lethality and move more towards resilience and disruption, excuse the abstract words. Increasing weapon damage only make the class better at sitting in corners and gunning down people and increasing health only gives the player an edge on first encounters (which can be extended by a medic of course but its still lame).
You need to have something where the assault guy becomes interested in hitting as many people as possible. This is where movement slowing hits or hits that gave bigger pushes or incendiary weapons would work well. Then there’s value in shooting multiple people and then repeat if necessary.
That’s how my tank in WoT works as well. It has high explosive shells rather than armour piercing shells. Armour piercing shells do lots of damage to the hp of the tank but rarely hit the vital parts or crew members. High Explosive shells don’t pierce the armour but give such shockwaves that it destroys or damages the engine, the tracks, the gun, the radio or kills a few crewmembers. This way my tank is oriented towards disabling others rather than killing them, my job is to go around and maim as many tanks as possible and leave the rest for my team to clean them up.
The Warrior in WoW can be geared towards this as well. It’s good to switch targets often because you apply all kinds of debuffs on them, the more you can deal, the more control your team gets and the safer the support and damage classes are.
