Im an avid oak player. Ive played both specs and id like to discuss my conclusion.
Assassin oak is almost in every situation more effective than general oak.
Ive played oak going full morale with minions, as well as penitence instead. the problem i run into is squishiness. the game turns into me sending my minions around, but as soon as the dg catches up to my oak im cat meat. a dg is really only getting to get tore up by your minions if he stands still, if not he will just outrun them. Erubus as a general is far more effective due to bite and regen which allows him to tank the opposing DG, allowing his minions to bring the pain. Oak doesnt have that luxury.
What Id like here is to hear your opinions on my conclusion, and maybe give me some pointers if theres something i havent considered. I really would like to have two specs to pick from . as it is right now, when i go general the game is much , much harder.
