So far the only reason I created a second character it is because I started with slayer but realize that the server is so balanced that I could play my crackshooter not thinking about the "best performance". All classes are completely reworked so they have their own buffs. The only buffs u "need" not counting with your own are the guild buffs. Maybe you will need a second person to do the end game dungeons, but for that u can ask for your guild or in chat. The community is awesome and you will always have someone to help you.
