Posted this in another thread already but was wondering what other people had to say about this;
How about making mass dispel capable of removing 'ground' effects, e.g. Consecrate, DnD perhaps even the warlock summoning circle. This way mass dispel feels yet again a little bit more special than usual and in all honesty I can't really see any balancing issues when it comes to pvp; mass dispel already costs a chunk of mana while all these other moves barely cost anything.
The only place where this could be overpowered is in pve where it removes like fire and shit (Which can be disabled of course)
