Blizzard and its sycophantic followers don’t want to admit that both versions of the game can exist at the same time, even though classic and numerous other gimmick versions already exist at the same time. They make the excuse of “we don’t want to fragment the playerbase,” even though they are already fragmenting the playerbase. They give you an excuse as to why they won’t do something they don’t want to do, but it magically doesn’t apply to anything they want to do.
Edit: Decided not to feed dumb trolls or repeat myself. Original post was clear enough already.
