What is this I dont even...
1) Invitation Scrolls don't even really give you an edge or any sort of advantage, so missing out on a code is really not a big deal. And as always if there's particular drops/items from the scrolls that are wanted, it doesn't kill anyone to suggest these items be made available in other ways.
2) People have been claiming "game is dead" ever since the first packs, so that's nothing new.
3) Returning Warrior was actually in the game for far too long and only incentivized people to have alts on friendslists left logged out for x amount of times to farm.
