They posted something about how what they said was that they'd always have it for "a single price" or something, which is... odd. I mean, is bundling products really something out of the ordinary? Whatever I guess. My one friend that didn't buy HoT most likely won't buy PoF either, so not a big deal personally.
You know, I literally never bought Factions because I have Prophecy, Nightfall and Eye of the North, but Factions never became discounted enough to matter, they just bundled it in one of the packs. I don't need a pack, I have 3/4, but to buy Factions was the same price as the pack.
