Tonight we killed Primordius in 25 man, leaving us at 8/12 after roughly 8 hours of raiding spread over two days.
The first 5 bosses fell pretty easily, but i feel like once you reach Ji'kun the difficulty steps up a bit. We killed ji'kun, Durumu and primordius in tonights raid and Primordius were (imo) the hardest of all the bosses we have killed so far (which makes sense since he is the boss furthest in the raid).
The trash can be a pain in the ass, but alot fun happens when you wipe more on trash than on certain bosses ;p
Have anyone killed several bosses on 10 and 25 and can comment on which felt harder?
