what could be cool, is the support class having a tile effect spell that slowly damages the player on that tile, all players on the healer that cast the spell's team including the healer, gain health equal to the amount lost by the enemy on that tile. This could have some interesting chase prevention tactics if placed correctly. the spell could do 5 dmg per second, so spells like Iceshade can increase the time spent in it, or even just strategically teleporting around your opponent to block off different ways to escape.
