Instead I have settled into these builds:

My Widow... just runs "Super Stock". I like the concept behind the stock build, so I simply streamlined and made it more optimal at doing just that.

My Delta probably seems a bit oddball, but the torso MPL give good punch, and the arm PPCs, range. Why the dual TAG in the arms though? Well, I needed something to push the PPCs into the upper slots. I tried it with lasers, but they didn't really pair with anything...and just made my already too hot mech, even hotter. I realized that TAGs are 1) no heat 2) would still push my PPCs higher, 3) would act like laser sights and actually tell me when my PPCs have clearance, and 4) my LRM packing teammates appreciate it, lol.

On my primary the Collectors 6R, those quirks work nicely to pack that combo of PPCs and UAC5s, and the UACs give great low heat volume fire while my mech is cooling down.

I was having trouble integrating the missiles into a cohesive build, but noticed one thing wit my WHMs, is they were still pretty easy to Light swarm. So since I want all my chassis to serve a different purpose, I equipped it specifically to fight lighter mechs.

well... this one is simple. I need a stock one for Stock Mech Matches. The Pink is because...well..why not, lol?
I refuse to remove the PPCs from the arms. That's is like playing a Modern Air Combat game, and removing the GAU-8 Avenger Cannon from your A-10 to mount more missiles. Espècailly since I see no purpose making a vanilla clone of builds my Grasshoppers and Black Knights already run... and run better.
So yeah, no LEET Tier for me. I'll live. Plus I still find them a lot easier to aim and track with in the arms. And I like the pitch control. But as with most things.... YMMV.
How about you? You keep PPCs, you keep em in the arms?, you make it into a dakkaboat? Not a PPC to be seen? What did you settle on, why, and how is it doing?
