What are berserkers like in EQ?

[Reiker]

They were made only because of the bad weapon dynamics in EQ - 2 handed weapons were very rarely used so their solution was to just design a class that can only use 2h.

They could have easily tied the Berserker class into Warrior if they really wanted, say there's an infinite use disc that puts you into "Berserker" mode and drops your tanking by a ton but increases your dps to berserker level, and makes Taunt become Frenzy while under the disc. Frenzy and Volley inherently need 2handers to function well so you really wouldn't even need the 2h requirement.
