I like the combo system in PVP. If you have a 1-2-3 combo, the same button switches from 1 to 2 to 3.
There's a plugin that does this thing, but I think I shouldn't have to install it to fit all my stuff on my bars.

Samurai is a nightmare in that regard, and while they removed 2 buttons for EW, they also added a bunch of new ones, so there's no real change.
