While archers, keepers and arcane wussies have it way easier. It is way more forgiving. You are basically encouraging range and magic class over close hand combat indirectly.
True but that's always been the case in every game that features strong projectile weapons, whether you call them bows, rifles, lightning bolts, or biotic powers.
It's the same way in real life: ranged weapons rule. Nobody fields an army of guys with swords any more.

On the topic of the Reaver, I feel so privileged to be living through this. Someday a year from now I'll be in a party with some n00bs and I'll be able to say, "Back in my day the Reaver healed with every strike during Rampage." And the n00bs will say, "No way dude, that's crazy broken!" And I'll just sigh wistfully into my headset microphone.
