Is there an ace2 autobuff addon like Smartbuff only more simple (without any party/raid options). I just need to cast Arcane intellect, Molten armor etc. on myself with mouse scrool wheel and still able to zoom camera with it (just like Smartbuff)
SmartBuff actually unbinds the mousewheel when it's installed and adds the camera zoom in/out functionality back to it itself. You can see this if you have SmartBuff installed, but disabled - then going to the keybindings menu, you will have to rebind the mousewheel which will unbind SmartBuff.
Anyway, I use CorkFu - you create a macro that says "/click CorkFuFrame" and then can just click on that (or bind it and hide the button).
I actually do use SmartBuff to buff the raid. Arcane Intellect instead of Arcane Brilliance. It has a few extra features, but that doesn't necessarily make it bloatware. If it's poorly coded, that's a different matter, but it's still the best for my needs.
