I see constant threads in the forum saying that pyro is bad for mercs, all i have to say is that im lvl 32 and couldnt be happier, wedo have a slow read your talents, if you specced it your fire dots put a slow on the target, and i unload and PS refresh Rail shot wich is a hard hitting ability not to mention that you do a butt load of damage to a burning target, in 1v1 fights i almopst always win and if i die they die shortly after. ohh yeah and heat is fine just time your shots cause if specced rail shot has a 100% chance to vent heat and spec for the vent heat reduction. so for the most part dont ***** about Merc pyro its fine just learn how to play it
