Gotlung is awesome but if its equipped it should be spooling and rdy to go. If you want something similar but without the spooling and with slightly better accuracy you have the chinzor. And if you want more accuracy for distance but less spray-n-prayability you have the maximus. The heavy can be very useful if you have a good team-oriented team otherwise not so much.

I am really torn about the heavies usefulness atm which is very unfortunate especially since the other body types seem to have their roles balanced pretty well. Here is where the heavy flaws out due its pros. I have 3 main characters right now which are 1. A medium engy / soldier 2. a heavy medic / soldier and 3. a Light operative / medic. What I write below comes from experience leveling all of them to lvl 20.

1. The heavy is a bigger target and is pretty much stationary when firing his heavy weps (especially the gotlung) which makes him a massive target / bullet sponge.
2. The heavy has pretty much zero maneuverability meaning that if you try to sprint around a corner to reload or slide behind cover to avoid bullets you will only live 10% or so of the times you attempt it.
3. The heavy weps given aren't powerful enough to make them better in close range then most of the SMGs. What I mean by this is that even as a fully buffed heavy with a spooled up ready to fire gotlung, you still will get mowed down by a medium or light running circles around your immobile @rse more times then you will mow them down. I cant tell you how many times I have ALMOST killed a medium or light but they barely lived because I have to stand in one place spraying while they run, slide, and wall hop around me while I try to shoot them.

This game is built upon run and gunning hence Brinks term "never stop moving" but the heavy basically goes against that. My heavy medic / soldier really shines when I dont equip heavy weps (AKA an AR and a SMG) or when I make him a medium. But I dont want a heavy with an AR i want a heavy with a heavy wep.

At this point when most people see a heavy they think "oh hey theres a fatty that cant run away Im gonna rush up to him and pump him full of SMG rounds before he can spool up his pee shooter" instead of what they should be saying when they see a heavy "Oh cr@p theres a heavy I better wait for backup or take another route."

As far as im concerned the heavy either needs more health or his weps need a buff in the damage department even if only a slight one. Personally Id rather have the weps do more dmg then the heavy get more health though.
