Advice for heavy armour shotgun build

[Dja303]

I found this build elsewhere on the forums:https://underrail.info/build/?HggGAwcNAwbCoGQAAAAAAFVQaQB4czdGVQAAAAAAwqBaJCbCsB7ClsKDFlVQRUTCjxXCmMK1wqQx4qa4A-KnggLis6wF4rewBd-_
It looks more or less like what I'm going for. Since i have yet to beat the game, I'm just looking for something simple to get through the game on normal.
One thing i don't like about it is that it doesn't have disassemble. Although as much as i like that perk is it really worth dropping grenadier? or is there something else that i should drop? I'm not too bothered about throwing skill although it is really useful. One more thing i would like out of this build is persuasion skill although idk if it's that worth it. Also do i really need 105 pickpocketing? it seems like a lot of points to spend there.

Disassemble is bad perk. Simple. Very few perks are worth dropping for it.

Thanks, i should have thought so since so few builds i've read recommend it. It does kinda seem like it would only help at the start of the game when components are more scarce and quickly become obsolete. Honestly should be a QoL feature for the crafting system imo but probably not worth sacrificing a perk slot.
