Honestly, as Sion, I thought these things would bother you:
Allies (or enemies, you don't care)
Running out of enemies
Your axe getting cold
When "it" breaks
Running out of bones with which to pick your teeth
Being kept from battle
Insects
Demacia (esp. its gates)
Un-severed heads
Swords (they lack heft)
Biting gnats
Spells with the intent of stopping you
Flailing
Unanswered wounds
Waiting
Not actively killing (see waiting)
Having a funny bone
Worms
Puny bodies
Jarvans (plural)
Bleeding (you don't do it)
Not knowing what you are
Hunger (it gnaws)
Quiet (it eats at you)
Waiting (you really hate it, so on list twice)
Marching
Enemy lackeys
Enemies hiding behind lackeys
Enemies dying too quickly
Unstacked bodies
Fear
Puppets
Being stopped
COWARDS
Cowardice (it will be met with death)
Sneaking enemies
Yordle traps
Fleeing enemies (it's futile)
Cries (they disgust you)
Non-dismembered enemies
Losing
Easy wars
I really thought, as Sion, that you would hate those things more than your title..
