The whole mine area seems to be oriented for lv26-28, making it a cool alternate site to Poporia. Everyone was caught on the SM spam craze however, so this place was devoid of people. I think many people are going to miss it on next CBT.
That BAM was the highest level thing in the area, but there were other bams of the same type as the SM boss that were level 27-28, which were actualy harder than this, at lest for me.
Another fun note: we went to fight one of the kumas in the south west desert, which I think are like lv38, and after about a minute of hitting it the thing was still at 100% HP
Figures. It didn't seem to hard to predict, but as a melee I got caught up on the fliping AoE you say because, well, I decided that it was going to do some directional attack and I was safe behind it. Bad call, seems

Friend messed up on a leap on the silliest of moves. It does a circle attack and he was just leaping out of it every time, but this time his leap was on cooldown and he didn't notice. Kaboom, full HP bar away :3
