If you dont like Blizzards new instant questtext display and you hate slow questtext also, then this addon is something for you.

Personally i find instant questtext a killer for game atmosphere.

You will have much quicker - but not instant display.

QuestTextFade_BdA comes without any fancy menus because it is basically only one single command.
If you want to play around with different speedvalues edit QuestTextFade_Bda.lua on line 31 and change the number value in 100 steps.
