I disagree, in Many vs Many gear isnt such a big thing in Ro. Maybe castspeed for locks but beside that its a pretty small factor. (Where it matters much is ofcourse in 1 on 1 fights)
I wouldnt overrate gear, especially not stuff you get out of boxes.
Theres games where you get like 50% less damage, 10x more dmg etc with gear where it doesnt matter what buttons u still succeed due to much better items eg. Thats not the case in RO.
Still id like totally even gear for all players from the fighting aspect - problem is, a MMO needs aims the players can head for and, without gear to grind for many players would lose interest pretty fast
