I'm in a position where I can get tons of useful support perks, but some of my Level Perk opportunities are useless to me even with squatting. If only there were a way to cash Perks in for more skill points. Maybe a level worth.
I don't like all 3rd level perks too, so you can take Skilled trait, skip perk on 4th level, wait for 6th level, and pick 6th level perk, then do the same with 8th level, skip it, wait till 9th, take 9th level perk, this way you'll lose only 1 perk (12, 16, 20, 24 vs 12, 15, 18, 21, 24), but you'll get 5*23=115 skill points.
Btw it's effective for sneakers, if you don't need weapon handling on 3rd level, you can take skilled and just don't take Ghost perk, because all bonuses are capped at 300 anyway, and with so high skill points you can max out sneak even with 200% weapon skill and replace ghost perk, because you'll
always get "benefit" not only near walls and you won't lose any perks at all.
