BLeh I still haven't been able to find the reason why my mainbar disappears when I shapeshift on druid :( No replies in the other thread, but I see druids posting about using it so I guess there IS a solution? I play 8 chars and having to drop bartender because of one of them would be a shame, its really nice except for that druidstuff
You say it disappears, but are you sure? It is probably just swapping in the bonus bar and you don't have any spells on it. Try dropping your cat/bear form spells on it and see what happens.
My main is a Druid and it works fine.
