Heroes of the Storm Build Guides
Prayer of Mending is pretty solid, but I think it would work better in the W slot, and instead of Flash Heal (too similar to Uther's main Q slot heal) you could instead choose 'Smite' which perhaps could look something like:
Smite
Mana Cost: 50
Cooldown: 6 Seconds
Smite your enemy with holy light dealing X damage and healing a nearby ally for 50% of damage done.
With talents to increase the damage or healing (depending on spec/build), it could make for a really interesting support/damage hybrid.
My only other constructive criticism is sadly Dominate Mind ultimate. Eight seconds is simply too long in an arena fighting game (MOBA) to lose control of your character and have it turn on its allies, especially with a 'huge range' and only a 90 second cooldown. Rather than losing the ability and feel for the character altogether or increasing the cooldown to a stupid amount like 180 or 200 seconds, a more balanced version of this ability could be the player loses control of their characters movements and may only activate their abilities and skills. Not only would it be entertaining, but also tactically interesting as you steer somebody away a second before they activate a carefully aimed ultimate or snipe shot.
Regardless, a lot of hard work here. Good job. :D
The rest seems to be pretty nice.
