Yeah well, thats why i deleted everything before this, chars, realms, all gone, there will be times during this EA that sh-it will break or even get wiped.
My advice is dont get attached to anything, dont hoard or grind too much, i dont know how updates work to be fair, but i think wipes are done to avoid conflicting crap and bugs, im pretty sure the devs will do this before that big coop upgrade in the roadmap for instance.
