I Can’t Do 5 x 2 (but I can rhyme)

So… 5 x 2 project.  Read about it here.  The idea is that you’re supposed to be able to bust into combat with a total of 11 abilities hotkeyed.

However, as a holy priest, I have a LOT of spells that I use all the flippin time!  I won’t bore you with the details of my SPECIFIC keybinds, but here’s a list of core abilities I use in every encounter.

1. flash heal
2. heal
3. greater heal
4. renew
5. prayer of mending
6. prayer of healing
7. circle of healing
8. holy word: chastise
9. binding heal
10. dispel
11. chakra (I’ve counted chakra as 1 key to slim down the list, even though most priests use at least 2 chakra macros (1 for each chakra state).)
12. fade (that’s serious business)

Oh noes, that is 12, not 11.  I just don’t see how ANY of these can be excluded!

Situational abilities that MIGHT be excluded…

1. mass dispel (one could argue this is situational for the encounter)
2. cleanse disease (one could argue this is situational for the encounter)

Now, you can argue that if these abilities are not needed for some encounters, so they can be taken off your bars and then put back as needed.  Totally valid point.  My problem with this is muscle memory.  If I keybind cleanse disease only for encounters that HAVE disease, I’ll be fumbling for it.

Cooldowns that are used a LOT and need to be used QUICKLY (and probably need to be keybound)

1. guardian spirit
2. life grip
3. desperate prayer (which I use a lot)

Even the ones that might be used once per battle are not the kind of things that I can be late on.  Fumbling with clicking the mouse for Guardian Spirit?  Dead.

Long non-urgent cooldowns that can probably be clicked

1. fiend
2. lolwell
3. hymn of hope
4. d. hymn

My bare minimum arsenal of spells without ANY cooldowns is already 12 spells, not 11 (close!). Including my immediate cooldowns puts the count at 15 abilities.  (However, I have all of the above keybound, along with my racial, bringing the total up to 22).

TL;DR 5×2 doesn’t work for me as a holy priest, because holy priest has a lot of bells and whistles – and disc isn’t far behind.  (So I bought a Razer Naga.  Right now it’s blowing my mind.)

Does this mean that some classes are more accessible than others?  Or is it expected (by Blizzard) that we’ll find our favorite spells and ignore some tools in our arsenals depending on personal playstyle?
