Not in the support sense of other MMORPG's where there is a character giving heals/applying buffs/etc lol

But there is more of the supports like Bowmen, standing in the back offering support fire on the target while the main offensive is at the front lol Maybe having a person with a high speed/sprint skill running around shoving health crystals/potions down peoples throats as they need could be considered support xD THough with the switch system most people can take care of their own health item uses lol
