Frontlines is ruined by exploits, SE need to fix it

[Tyrial]

Just taking a moment to point out that a single healer can out-heal the DPS of two DPS, and an unburdened healer can out-heal three or more.

Game's not balanced for this. There needs to be limits.

I fail to see your point. There's always a solution to a problem. If that's the strategy that your opposition chooses to employ then you need to find a way around it.
