1 2 3 4 5 6 7 8 9 0 - =, Alt 1 2 3 4 5 6 7 8 9 0 - =, Ctrl 1-6, and have my executions set to a bar that i swap for my first bar on the fly, and swap back when the execution goes off.
This is as a level 50.
It may sound like alot, but there is alot of non-essential abilities made for certain circumstances, they're the ones set for obscure hotkeys like ctrl+#. Using Alt to access a secondary hotbar should be second nature to many MMO players, And switching between top bars works flawlessly when you get used to it; much better IMHO than playing finger-twister with my keyboard figuring out a new set of hot keys.
