No one is forcing anyone to use their hard earned, real life currency. I have been disgusted at all the complaint threads I've seen. For one, both the mythic and arcane pets are garbage. There's no need to buy them or even desire except to look "cool" because arcane is so rare. Secondly, does anyone that complains know what "incredibly rare" means? It means you will spend a lot if you really want it that bad. Just hold off for free, highly time consuming drops.
