Restoring sanity to Channel Divinity: Restore Health

Following in-game feedback (and the ability lack of sense), here's the new take on it. This way, PCs won't have to bash each others on the head to reach 1/2 HP so it can be used.

​
​Channel Divinity: Restore Health
​Starting at 2nd level, you can use your Channel Divinity to heal the injured.
​As an action, you present your holy symbol and evoke healing energy that can restore a number of hit points equal to 5 times your cleric level.
​Choose any creatures within 25' of you, and divide those hit points among them. Undead creatures and constructs cannot be affected by the spell.
