There are so many “inconvinient” things in Classic. Should Blizzard fix them all ? No.
Inconvenience is what make Classic so special, make our choice matter etc…
I don’t care about dual spec being implemented but it’s a WOTLK feature, it should stay in WOTLK.
Else, in WOTLK you’ll get players asking for Cataclysm feature just because “it’s coming 1 expansion later”
