First it was OP because of its veterancy (to much HP after veting up), then it got nerfed to extinction and now?
Two bursts against a unit in a building aaaaaaaand wipe. Relic buffed the flames (for every one, ok) but reduced the cost of the upgrade for the Halftrack. It gets two Flame-throwers, the second one for the half price and its range is insane.
I think the problem is manly against buildings but also against support weapons outside of them and i believe that it is a little OP at the moment. Its the best Flame weapon in the game and you can have it so early!
Just look at this if you are not convinced

What do you think?
