Well, the ideas are nice, just there are a tons of bugs.
Common:
-for hell knows what reason it always restores my heroes cooldowns...
Admiral:
-Morale slice only decreases the friendly heroes' attributes (so when i tried it on the paladins nothing happened except it wrote "morale slice")
-Demoralize: use a trigger to remove timer windows
(event: a timer expires - switchback timer; condition: none; action: timer - remove expired timer)
I c you wanted to destroy the last timer window created, but that's not always enough (especially if i can cast three or four demoralize at the same time because of another bug)
-Morale Aura: when my admiral dies it will no longer give him attribute bonuses in his next life
-Confuse: it's mainly bug-free, and has a nice effect

Marksman:
-wooden bullet has an infinite stun. set the Duration on heroes and units to 0.01sec
-charged shot: it's quite nice and bug free, except it allows to shoot himself

-multi shot: there's no problem with this...
-sacrifical shot: i think it's bug free too, and slow motion deaths are very good!
This is just a constructive critic, if you can fix these bugs this'll be a nice spell!
