Epidemic and Dazed?

If I daze a enemy with concussion shot, can I use epidemic to instantly daze nearby foes?

Yes, but Epidemic has terrible range and costs 15 mana.

Just for example (I love to bring this up against Epidemic users) if two warriors are attacking the same target, but standing on opposite sides, Epidemic won't reach from one to the other.
