Well i assume you gonna bot, this means you would need a working weapon switch. Weapon Switch is not that well workin on the free bot (which is based on keypressing) and your Eu char will die alot due to to the bad Equip + Pot Delay. Eu Chars are always hard or harder to bot then chinese, Chinese are able to survive lot more alone, thats why i suggested to take a Chin char. If you really insist to be a Eu char, then i would go for Rogue. Rogue is Full Str, survives a bit more then a Wizzard, and also lvl fast (along with Subtree Bard you will lvl pretty fast) and Rogue is also fine for killing Uniques to. To lvl fast and farm less i suggested only to farm on Rogue the Crossbow Skills and not Daggers since they are mainly used for PvP. cSro is not like iSro, you wont find much good Equip parts so mainly you will use NPC items till 7D / 8D ~ .. still your choice though ..
