RAIN OF DEATH seems a bit broke

[syntaxlies]

Rain of Death
Delivers a ranged attack to target and enemies near it.
Combo Action: Quick Nock
Combo Bonus: Chance to inflict Stun.
TP: 3000 / Recast Time: 30 sec.

Somethings been bugging me about bard and I wanted to get some other opinions on it.

Rain of death has a 30 second cooldown yet it combos of a skill that has a 3 min cooldown. To me this seems pretty broken. There are tons of ways this can be fixed like.

option 1
make it a solo action like jump maybe with a 1-3 min cool down.

option 2
make it combo before quick knock(might suck since its aoe though and you may wanna get that quick knock off without aoe'ing)

option 3
give quick knock a 2 min cooldown and rain of death a 2-3 min cooldown.

option 4
make a new combo that consist of only heavy shot>rain of death

option 5
combo off quick knock but change RoD to 3 min cooldown so at least the combo makes some sort of sense.

option 6
keep it the way it is but lower tp to 2k (2k seems much more reasonable for a non-combo RoD0

option 7
a chance to stun when not used in combo

So lets here some feedback from all you barchers so that I dont regret posting this in bard instead of general discussion.
