I might play it so I can properly clear Ulduar HM and ICC hc but that's the only content I am intrested in. Looking back I think the only reason I enjoyed WotLK cause of the guild I was in so might just not touch it to save the good memories. Cause content wise I think it's actually around the level of BfA and only slightly beter than WoD and Cata. Now TBCC on the other the content is intresting I just don't play cause I can't properly raid in my current situation.
The 10/25 man being the same raid ID is a Cataclysm thing though so no matter what WotLK patch Blizzard uses it shouldn't be in unles they really go for a big change.
