While lancers being dicks that kick zerkers is true, being a level 60 Zerker I fully understand just WHY I am being kicked. Many high level instance final bosses are dps races (see Balder's Temple), many requiring the group to kill adds while fighting the main boss. While Zerker may seem like they shine here, the need to charge for extended periods of time really screws you over in boss fights like this. It is entirely possible to beat these bosses (even hard mode!) with a berserker in your group, however its just like having an archer. The instant burst dps isnt there.
Berserker buff was announce on kTERA site, but theres not really any specific details or translations out there. Also, considering there's not really that much do to at 60 other than farm and do daily quests for accessories, I'm quitting my berserker and going lancer, at least for now. The bright side here is that all the extra plate gear I'll get from instances at 60 where I refuse berserkers will be able to go to my level 60 alt berserker lol.
