Yes, I still use the master and slave keybinds, mainly because I use the alt+1, shift+1 and ctrl+1 modifiers for separate abilities.

I've thought a lot of setting up a target and hold approach now that I'm doing instances again. If I can find an easy way to quickly switch between the two methods, I'll probably do it.
I'm mainly waiting on the patch now though, to see what macaroon 3.1 is capable of.
