in the end you will need any class what you can get if you aim higher than FoG or something else.
Skip the Tank you will mostly need it on Siege if you plan to go on Siege.
Titan,Warcryer,Warlock,BD,SWS,Prophet,Shilien Elder is the way to go as a Melee DD. if you cant afford high gear at the start build some little melee helper for Example. Phantom Summoner which is a great Party Healer and dont use any Mana for his heals.
