Bad idea bosses on every map.

I used to hunt bosses at the beginning of a level when the experience loss from deaths didn't hurt.
Now I'm doomed to play low-level maps, so as not to take risks.
I leveled a warrior who can handle T12 maps, but still can't handle T12 bosses. Losing everything you've gained on a boss who you know will map you in one hit isn't fun.
There's also the problem of whether they put the abyss area in the boss arena. I ended up with a double boss.
