Heh...filling your character macros up on one toon? For druids, I might understand that.

My mage gang is 45. I have the following character-specific macros:
Arcane missiles
Buffs (all of 'em, castsequenced)
Trinketed fireball
round-robin counterspell
Trinketed fire blast
Focus switching
Follow
Mount
round-robin Frost Nova
round-robin Sheep
PoM-Pyro
Scorch
Wand


So 13 in all, plus my usual ones on the General macros tab:
Accept everything
Assist focus

My warlocks have a few more macros for fear, death coil, soulstones, petattack/petpassive, etc. but even then they don't use all the slots on the character tab. :P Combine abilities that make sense...it'll not only save macro space but will save you lotsa time and headaches when you stop micromanaging things. Good macros work FOR you.

I'd share what macros you're using as has been suggested. Might be we can help you minimize/simplify things a bit.
