Yes because nothing is more exciting in a new expansion than being forced into last expansion's content in order to level from 60-70. Doesn't solve how they will be halted from progressing the Main Story because it'll be locked behind dungeons every few levels.

If they care at all about the health of this game, they will not release only DPS for an expansion. There's a reason why every expansion of WoW's that released a new class made sure that class had a tank spec, and we know that Yoshida and his team very much pay attention to Blizzard's successes and mistakes.
