If heavy weapons requires a lot of strength, I hope the skill and feats scale with strength and not perception, that would be a serious faux pas in game design that the new weapons in a new dlc called Heavy Duty requires a lot of strength but only scales with perception. If you did this mistake Styg, you get a couple week to fix it.

It's nice when there exists builds that are not just about maxing one stat.
I get your point when it comes to High-Technicalities, which always seemed to me like a poor excuse for investing in Int with guns.
But Strength checks are usually like, 10 at most. You can get that at level 1, and still max Perception after that without compromising anything. Your dex, agi, and will are probably gonna be at 3 anyway.
