Hmmm i agree on the points you guys talking about I think leveling should reward in Customization....

this thread is getting long
Anyway, basically everyone wants to be sure that there won't be high-level n00b-slayers. I think that you could either
1) Not make higher-level characters have any physical advantages (more effective equipment, better stats)
or...
2) Group players based on their level (ie: 1-10 in one server, 11-20 in another, and 21-30 in the third)

Brndobin, yup, second option: autobalancer. It's not only about levels, but also about armor, weapon, other items, upgrades, so each player have his own "weight", and the balancer use it to group players for match.

so... wrestling-style weight classes?

sorry 'bout the double post, but is there any sort of single-player options planned at the moment or are you focusing exclusively on a multiplayer game? (also sorry if this has been asked and/or answered before)

PVE content - maybe, in future, but if you mean "single player" as part of the game that will not require a connection between client and server, then the answer will be negative
If you mean PVE, or training fight with a NPC... who knows? We have a lot of cool ideas

Could we see Co Op or a Arena for training ?

one-time or seasonal "Event" type co-opable boss fights for special items would be awesome in my opinion

Ye i love events.... i wanted to see some random boss events too

Yes, we're thinking about co-op, bosses and other PVE events. Nothing more to expose, sorry - working on PVP part right now
