Kink

A lot of people are saying to down gruul first before you move on to SSC and TK. But the trash drops some fairly nice epics, fairly often too. Not to mention vortexes for T3 weapons.

So personally I say if you already have Maulgar, then just give it a try to see something different. At the very least you might get some nice trash drops.

There is light at the end of the tunnel.
The only problem is, it's often an incoming train.
