Ok, imo better start with the basic stuff, do you rly want to play as human with humans stats and maybe pick the top DMG class, im telling you that as a human/Sagittarius! There is a difference when you are dark elf and ghost sentinel, dmg will be better, survivability will be less, but we play a version of the game where in pvp 1 shot is common.
Items are not cheap now, so if you are on a budget, choose wisely, try to get the best item for best price, if you are not efficient with archer you will not be able to farm fast, while using aoe, I am sure about items you will learn all on your own.
Cheers
