I tried Anguis with a pickup raid.. Dang he was tough.. His AE's was terrible and that was what killed us. Some said he only did frontal AE's but it appeared that they were PBAE's. Not sure though since it was a dot so people could have gotten doted before they found a good position behind the mob.
Really not sure what you mean, but Coldtooth is up and terrifying way down south in TS, near Ogdin Boulderboom the quest giant. He has some pals with him - many many arrows... <shudder>
