But let me take a shot in the dark I have seen a lot of complaints that these pre-set quirks have taken the "custom" mechs out of the equation and created "pre-built" chassis for everyone to run.
Wanna know how I think you should fix this? Make the quirks select able based on the chassis being run.
You wanna don't/can't run an ac20 on an ATLAS, well thats ok, throw and XL motor in and switch over to the Gauss Rifle quirk. You wanna run LPL's instead of PPC's on an awesome? That's fine as well, change your quirk to YOUR build and run YOUR mech YOUR way, not PGI's way.
Let US choose the way we want to run our mechs and you will always have my money. Are you worried about balance? Stacking up on sick perks that make your mech unstoppable? Fine, than do this, if quick A is chosen, than quick C or D cannot be chosen. This limits stacking but still allows customization, AND its all simple coding

And as a side note, I dream of the day when 12 IS take on 8 Clan mechs that aren't nerfed...with weight limitations on both sides.....the true and only clan way, superior firepower and pilots...but less of em.
