Rock, paper, scissors could possibly work. Problem is that, as is, its more 'rock, rock, scissors' if you're a mage. You're pretty much entirely forced into being a half-ass support with occasional damage output that doesn't even come close to comparing to archery or melee. The only place that mages really shine is in the water because you take away melee ability to hold W and win. They can still beat you if they have swimming, and more than two brain cells, but watermage is very strong.
Maybe having ele walls and other ele stuff will help, but I don't think that it will actually solve the problems that mages are dealing with. More tools, but not the ones that are needed to be viable in any kind of solo capacity.
