I realised earlier that my old addons didn't work when downloaded from here, as I was playing them from the extracted ones and not the "compiled" ones.

Anyway I updated the addons for b43. So you can use them if you want.

Both are intended to make the game significantly easier. (The one only for Stamina based classes).
