Not entirely clear what you're looking for.
I currently use macros such as:
to switch out my important (and therefore easily accessible) Cat form abilities form Bear abilities while in Bear form.
/cast [stance:3] Rake; Lacerate
/cast [stance:3] Ferocious Bite; Frenzied Regeneration
I don't use the default action bars, nor do I use action bar paging within Bartender as I just find it clumsy and more restrictive than helpful.
Other than that, A few things I feel are important when keybinding on a melee class:
- I want to be able to DPS while constantly on the move without any interruption or extra effort. This means keeping my primary damage abilities on keys that I can easily access while pressing my movement keys.
- I keep keys that are commonly pressed in sequence close together, and arranged in such a way that my fingers can move quickly and efficiently between them.
- I want to be able to press cooldowns, gap-closers and interrupts (off-GCD abilities) at the same time as I press my damage abilities. I don't want a delay, no matter how small, between activating, say, Tiger's Fury and my next melee ability.
- I like to keep to similar patterns across specs and across alts. Regularly used important abilities go on keys close to my movement keys, cooldowns tend to go on number keys, interrupts always go on R and so on.
If you are looking for extra, easily reachable buttons, consider unbinding walk backwards. I only find I need it when I'm playing tank specs so generally unbind it when I'm not. Also don't forget about the key to the left of 1.
If you want specific examples of how I bind the abilities you mentioned, I can do that too... I just have a rather unorthodox system of key-binding that probably doesn't work for anyone but me.
