Just tried him with my Shield/DM tank and as soon as the 2nd pet spawned I had to leave him and kill pets...which took maybe 6-7 hits but he was at full health non the less..this went on for 20 or so minutes trying pulling him, killing pets, putting him in lava...even had friend bring in rad def....this is the 1st time I can recall ever fighting anything that a rad def could not out debuff its regen...so plan C ...he brought in damage and killed the pets while I killed EB...yes, this was a challenge and I don't mind challenges but I have better things to do with my life than fight one mob for 30-40 minutes and I hate FORCED teaming....it's one of the reasons I don't play LOTRO much anymore...I team all the time but not everyone wants to run the same missions over and over..I have a lot of 50s and its boring enough without making it a chore...
Devs, you need to go back and fix this.
