...There is PvP though I have no idea, doesn't seem to be large scale (i.e faction) though, there is some arena thing.
..Can vary, early days for me and I'm training 2 jobs side by side and so far it's been fun.
..Awesome I absoloutely love the class system, which allows you to drag and drop skills from different jobs, change jobs etc 5/5
... Prices are..no idea, monsters don't drop weaps or armour so players make or buy from the shop and as far as I can tell there's just 1 set at each level, which you can upgrade etc, higher level players use the cash shop to look unique.
Um, there is a PvP in DOMO, buuuttt i dont really know much about it so cant help u there...I love the class system there is a variety of jobs to choose from, and you can like combine jobs to get more skills to use. Weapons and armors? You buy from the stores..there are like armor sets for beginners(lvl 10) and then more advanced ones. Same with weapons, but you can upgrade them..
and yea there are costumes in the cash shop you can buy too.
