hehe now after some time i think these classes are best
1.Paladin or Dark avenger-Im not sure cause both are great classes,great deff,good buffs,solid damage.Pala has AI and TOL so he can live a long,DA has panther which on olly rocks.
2.Overlord-Amazing buffs,good defense,best debuffs.Cause of mana problems draining enemy isnt best tactic so sometimes u have to go as Melee OL and u will still do good damage.
3.Gladiator-Good def,a lot of hp/cp,amazing damage and has lionheart to help him against mages.Has battle roar too help him get alive,and sonic barrier for 10sec ownage
4.Tyrant-Like gladi but i dont like him as much as gladi.Has totems,ff,zaelot,barrier but doesnt have battle roar to recover his hp
5.Necro-Summoner/debuffer/nuker.nuff said, but if ur summon goes down and ur curses dont land ure pretty much dead
6.Summoners-Summons always rock especially Magnus unicorn.
7.Bish-Melee bishop can be imba class for olly.I actually saw one bish with duals kill gladi ^^
