With the recent forum focus on both the Heavy Gauss and legging, it's become quite clear that more and more players are relying on Legging as their primary combat tactic.
As much as I wish this wasn't the case, I'm not exactly opposed to this, as a tactic is a tactic. However, in several of my recent matches, I've noticed that a particular player utilizes both the AC5 and RAC2 Partisans to exclusively leg Mechs. You wouldn't think this would be as effective as it sounds, but it's almost too effective.
As both variants have an actual range that far exceeds their stated ranges, are fairly accurate, and have none of the degrading trajectory of the larger autocannons, one can often sit passively in a Partisan on top of some ridge and snipe the legs off of Mechs at extremely long ranges. It's often much easier to target and leg slower moving Heavy and Assault Mechs then faster Light Mechs, and as all of the damage is being dealt to the legs, there's very little indication of damage received other than the rapid color change.
I was under the impression that the smaller autocannons were supposed to deal less damage against heavier armor, but the speed at which the AC5's and RAC2's can chew through leg armor on Heavy Mechs is baffling. In fact, I've had a brand new Novacat legged several times in about 3-5 seconds (probably an extremely inaccurate estimation), regardless of whether I was moving slowly or quickly. I don't stand out in the open, and can use cover rather well, but it seems not to matter, as unless I spot the Partisan either before or as soon as it starts firing, I'm probably gonna get legged before I can kill it.
I just want to verify that smaller autocannons do indeed deal less damage against heavy armor, and that this is not some error, but rather that the AC5 and RAC2 partisan are apparently very effective at legging larger, slower Mechs. I also wouldn't mind some sort of damage rebalance, as it makes little sense to me that 47,910 Cbill Partisan Prime can render a 100,000+ Cbill Heavy Mech combat ineffective in 3-5 seconds (again, probably inaccurate), as it's supposed to be specialized as an Anti-Air unit.
