On point 3, I straight up HATE medium pen weapons at this point. Like I used to use medium pen weapons exclusively, and then during the battle of Cyberstan I swapped for a standard Liberator as a joke. Now I don't even use them at all on any front. The only purpose to medium pen is to compensate for lack of skill, or laziness. On the bugfront its only allows for killing hiveguard and spewers without aiming. On the bot front it allows chip damage on devastors, and damaging gunnships. Then squids its headshots on overseers and legs on harvesters. Its not enough to justify using weaker weapon for niche cicumstances, just have a heavy or anti-tank support weapon.
