I was doing the Wayrest Sewers I on normal with my partner last night and I found the final boss battle to be very frustrating. My partner and I are both magsorcs and were both using clannfear pets to run through this dungeon for the first time, so a group of 2 DPS pet sorcs, I'm an Altmer and she is a Bosmer. I'm at about 675 CP and she is at around 705, we haven't optimized our CP at this point, nor do we have the best gear or weapons. Still we've done Banished Cells I, Elden Hollow I, and Spindle Clutch on normal in duo without dying. Neither of us died in Wayrest either.
For some reason Allene Pellingare was chasing me around the entire final boss battle, my partner was heavy attacking using a lightning staff to try to get her to aggro her and take the heat off me. I was using a flame staff, and flame clench along with mages wrath. I also had defensive rune up but it didn't seem to effect her. For some reason, the boss wouldn't stop coming at me, I spent the entire fight running backwards, alternating between light attacks and skills as well as trying to keep my defensive shield up. While we stayed alive it was like the boss didn't even recognize that my partner and the 2 clannfear existed. The boss was taking damage of course from both of us and the clannfear but she didn't even respond to those attacks.
Is this normal, a bug, or related to only having 2 DPS in the group?
