Full disclosure on Wintergrasp though…I’d much rather queue a Wintergrasp now than an Ashran.
I say leave Wintergrasp if you have to leave Ashran. For Epic BG’s, I currently have a 25% chance of getting Ashran. If they take Wintergrasp away, I’ll be at a 33% chance of getting Ashran. Either remove both, or keep both, or just ditch Ashran.
