I really like the idea too, it's neat.
I'm not sure how it works in WKC, but if you were damaging a leg, I wouldn't mind seeing him get back up after like say 20-30 seconds.
Make the fight a little more dynamic and coordinated. Possibly even allow you to keep him down longer if you keep one dude attacking his leg, the rest could focus on his head.
Even make it so as the fight goes on, it takes less and less damage to get him down.
I don't think BLM should take part in this, they can already hit any part, they'd be better off sticking with that. Guess you could add it though.
Maybe taking a mob down would limit it's ability to do some devastating weaponskill (a mage killer), but in place it would have another, say push back or stun, that it could defend itself with while it was down.
idk, just some more to add to it.
figured, I'd throw you a quick run-down of how hate works in this game incase you were interested.
In ffxi, hate would dissipated over time, in ffxiv it's constant. Once you've created hate, it's there till you reduce it or you die.
hate is 1 damage = 1 enmity; cure = .6 or .75 damage (so cures generate abit less enmity then damage.)
Most actions the enmity generated isn't noticeable, 15-30 enmity. (which is why stoneskin and regen rock as whm)
weaponskills that say increased enmity, the seem to double then enmity generated by the attack.
sentinel increases enmity generated by everything used during by 20%
Freeze seems to lower enmity by the amount of damage it deals.
What you really need to know is the blm stuff, basically just wait until you see the tank use a weaponskill, then start you're attacks. keep your eye on the hate meter, if the tanks decent, there's never really a problem. Use freeze whenever it's available and save chameleon for if you make a boo boo (if you attack after a hate reset, or pull hate).
I never played BLM in xi, but hates pretty easy in this game. If the tank dies, the fights usually over unless you're close enough you can just nuke whatever you're fighting dead.
If it's a tank you've never fought with, or you're not sure how well they'll keep hate, i always just wait a nice chunk of time before I start fighting (30ish seconds), it's just easier for me.
