Completely agree.
WFs would of actually worked well as a pseudo MOBA mode. Maybe with some micro on unit management. I'll never know why they basically turned it into a resource farming scenario. Probably one of the most unfun type of gimmicks in WoW.
And IEs, I don't even know where to begin. Can you imagine if we got 11 minizones with actual story and lore? I think it easily could of flipped BfA to being one of the best expansions.
