ive never spent microsoft points on this game and i feel like i compete in multiplayer quite well, i get mvp fairly often which is great.
the best bet is to just use those 40 happy tickets at the start wisely! i bought 1 armour set and 1 weapon set.
always try leveling up your items to level 10 it makes alot of difference, and as with most online RPG's you dont have to have the best gear to get kills just learn how to play your class properly!
TIP - use Mage!!
