Oh god, no.

Even tho I agree with most things said in here, the old Qi ranking thing is, was and will be worse than this ELO one. ..Really, everyone (and I mean literally everyone) hated that old QI = rank system. It made no sense, nor did give any kind of indication about anynoe's level of skill.

People actually requested ELO for a quite while.

I'd rather see something like modified ELO system, with added ELO decay, and possibly "ranked servers" or something.

And I'm one of the guys who'd benefit most from the rollback. I'd get from tank 800-1200 range to rankt 42nd or something.
