IT being a free range shotgun chance isn't really that bad... though it would be nice to see it split 1-60, 60-100
I do admit that it gets annoying to get wiped out by high lvl players but it is like a reward to lose to those lower to you, and as a 79 I've lost to many 65-70's, when that happens I cant help but enjoy the show.

Recoding to separate into such auto groups could be more trouble than it's worth. It would fix some issues but I'd imagine for each fixed a new issue involving it would arise.
