People will always whine it seems.
For all we know it be one planet, the new race plus a few new skills for the level cap increase thats pretty stander even when everquest 2 did some expansions all it was sometimes was just a new dungeon and a few cmore quests, or just a zone of floating isles.
So OP where do you get that this isn't normal for expanding a game?
Sorry no new race. Cathar will not be in Makeb. It will be available on the Cartel Market soon™
