With the new rebalance , pretty much every class can be just some kind of healer/tank/damagedealer.
This is SCI-FI not Dungeons and Dragons!!
Things like blinds, faints, traps, robots, smokegrenades, remote hacking, proxy soldiers, directional cloaking devices, make alot more sense. In terms of gameplay and also in terms of immersion.
If i wanted to play classic mmos i would play WoW with a sci-fi mod.
