or maybe try using it as an anti infantry weapon, im pretty sure its not an av weapon especially since ccp has never specified it as one.

Best area denial weapon in the game, in some situations/maps.

Being a dedicated user, I have run into some of the hit detection issues/aoe dmg occlusion and escalated them to the right teams.

I have had the ghost projectile pass through enemies, the hit with no explosion/dmg, the reloading without reloading, the shooting without the projectile, and that weird charge thing you describe

I agree about the scout suit build you're referring to. I've wanted to try this myself but I find that it is near impossible to fit a PLC on my scout suit without sacrificing more than I'm willing to give up in survivability or speed.

I think that the MD is good for closer range area denial. It is much better for keeping people around corners as well as spamming (which is what I think is this weapon's biggest strength). It takes little skill to use as an area denial weapon but what it lacks is enough power to kill instantly.

I think the PLC has a better ability to destroy threats from a safer distance. People hacking an objective are instantly killed. Snipers can be instantly handled from surprisingly far distances. When people get hit with a mass driver they are still able to get away many times. I still agree that the disadvantages are difficult to overlook with the PLC but I think that new users should try and use it as more of a "threat neutralizer" until they gain enough confidence in their abilities to treat it as a primary assault weapon.

TL;DR: I agree that the MD is better in most situations but I think the PLC has great advantages in other situations.

I get many kills on people who aren't paying attention at long range. Or if I know people are waiting to peak around corners. Or if they're in a doorway or at an objective. The slow travel allows them to dodge if they're aware you're firing at them but if they're not paying attention to the projectile itself (or focused on ADS) then you can still get many kills at range.
