If we revert it back to what it was in Vanilla it would take you a day before you came back here and complain about it. For some odd reason you "think" doing stuff back in Vanilla was fun when it isn't.
Player from Vanilla- "They should do this and this, make things a lot easier"
Other Vanilla player- "I totally agree"
**Few years later Change happens**
Current Day player- "This interface sucks, it's totally ruined this game"
Other Player- "I agree, just like re-used content"
Other Player- "You both are idiots"
Blizzard can never satisfy, what a shame.
