Gal Scout + Dumbfire anti-infantry swarms?

Methods of killing more OP than any weapon:
Logi-LAV 2MPH kills
Beta Dropship missiles
Melee Glitch
Cloak Shotgun (not the shotgun itself, but the ability to fire right as you de-cloak)

Weapons:

1) 1.7 RR
2) Flaylock
3) TAC AR/Standard AR
4) Grenades in general before the 1.8 nerf to amount
5) Viziam LR
6) 1.8 Assault CR (it wasn't nerfed as hard as everything else in 1.8, which made it come out on top)

Reasoning:

The RR did as much or more damage than the TAC and the CR and the Laser, and did it at longer ranges. Not only that but it was always hard to see where the person was shooting from when they're 100 meters away from you. The flaylock was only OP because you didn't have to stand still to use it. You could jump around your target and make it impossible to hit you while dealing massive splash to your opponent while you didn't take any. The ARs weren't OP as much as they were just clearly better than everything else. They also did the most damage at long range because you could burst fire them to get perfect accuracy (still applicable today). Being able to spam 3 grenades, and having everyone and their mother doing it was just stupid. 2 makes them perfect for tactical use (i.e. you don't just spam them like they don't mean anything). Viziam was only annoying in combination with the AR. It was also an accident. The DEVs admitted that the Viziam was never supposed to have 20 damage, and it should have been 16 like the others. If you were just up against lasers you were fine because you just had to get close enough to them. If they also had AR users though, trying to rush in with a HMG was useless. The ACR was actually not that great of a weapon in 1.7. I mean it was, but compared to the RR's range it just wasn't easy to get within range of the enemy. Now that we have cloaks and that the other weapons got nerfed, the ACR is now on top and can easily be used to sneak around and punish the enemy while their back is turned.

Weapons I've never considered OP
HMG
ScR
Mass Driver
Dumb-fire swarm launcher
Standard CR

Sniper HMGs.

The days when you could see slayer Cals with TAR + Contact Nades taking out LAVs at range

In one ambush I saw a poor heavy try to LAV rush a squad with TARs, they destroyed his LAV with TAR fire and when he bailed at the last minute casual tossed contact nades at him. I don't think he even got off a single shot and they were all just standing out in the open.

happy to see snipers were never a serious problem

How come the ScR never makes it to the list?
