I think that the game can obviously improve on its many flaws (unbalanced healers, genderlocked races, limited character customization, mediocre graphics, super super bad early game etc...) But considering the current MMO market, it is the best game right now. I bet thoug hthat if in 2-3 years MMOS arise again, this game will have to fix all of the above on their next expansion (balance healers, makes healers more fun, ungenderlock races, fix the early game, more character customization) if they want to keep up with WoW, that at that point, will be on their next expansion, and after seeing how legion came after WoD, I believe their next expansion will be absolutely amazing. Also, ESO could potentially rise, and there might be a new MMO that takes the crown
