people avoid sola because of the superb amounts of lag.

I loved and hated Unrest. It was more fun at lower levels. The ZEM is good, so experience is fast. But at higher levels you only have the basement group and the fireplace to choose form, and there's people still hanging out down there until their 30s. Competition for mobs can be fierce. After level 20, unless you need loot I'd say stay away.

I also hated Oasis. For a while the Orc groups were decent. Crocs sucked every time I did it. Slow experience, too many people, not enough mobs.

Uguk is my new favorite zone. I can usually find a group, people are competent and there's plenty of mobs to go around. I've done most of 20-25 in there. I haven't been asked to join in MM yet because I'm just now getting to 25 but I look forward to it, as with SolA.

The Painbringer won't proc until level 35, and at level 35 you are most likely going to be in groups with crowd control so that AoE proc is bad mojo. But it's a nice dmg ratio before it procs. Look at Obsidian Shards (proc at 16), Kicsh Der Pavz (at 20), Gnoll Hide Lariats (at 25). The tentacle whip procs at level 1 but it won't create much hate.
