That makes question is he really a vet if he cannot kill them. There is only few really good proto heavy light weapon users. All the rest just try to adapt. Heavy dropsuit isn't designed for light weapon. It's fuckin slow people with poor scanning and NO EQUIPMENT.
Use that knowledge next time. Any stupid flux + weapon with +10~20% more dmg against armor will kill him. Or go with dempners and sneak behind him with anything You want. RE are fun. Somebody told me that flux + nova knives is even more fun.

I don't mind if Heavies are using light weapons during this stage of the game. When all heavy weapons arrive we can discuss it later. And it is really good idea to make commando only heavy type who can use light weapons but... There will be time for this. Now let them use it.

What a bunch of QQ....

Heavy/RR combo is mostly easy to counter.

I'm on the other hand seriously concerned about the upcoming buff to the frames in combination with the current beast that is the HMG. Even nades will lose much of its role as the fatty killer, Will fattys be a must in future PCs in the city maps? I fear they will indeed....

So you don't know how to keep your distance and tear them apart by strafing left and right, while aiming at their domes? It takes longer to kill them than average but it can be done.

Get a heavy suit with it, and at least try to get an advanced RR like the SB-39.
