Sigh.
As it stands, a Fighter can't competently do more than one, possibly two of the following with their pathetic skill-points:
Climb a cliffside
Stand watch
Administer first-aid
Navigate the wilderness
Swim
Get through an obstacle course
Swing from a chandelier
Maintain, repair or build their own gear
Ride a horse
Take care of a horse
Guess how tough their opponent is
Know what they're fighting
Not fall for a feint
Know the battlefield's terrain
Guess the enemy's tactics
Lead troops
Know the city they LIVE IN
Know politics
Be GOOD at politics
I'd expect any competent warrior-type to be able to manage AT LEAST half of those.
The 'lol, Fightars r dum' meme is a pernicious one, and I want to see it killed. But Fighters are no good at killing memes, either.
