Shots Fired: A Machinist Guide

[KilluaKhan]

hey jus a few questions as a nub machinist..which stats are better for secondary stats (det,crit,ss)? i ask this for the best food to take...does det affect damage with GB on? , crit i like seeing high crit hits but i dont know exact numbers, and ss ive noticed for my WF burst..i seem to be able to fit in a extra attack. but i dont know which is more effecient for duration of fight.

also another question is after looking at most rotations posted here..i wanna ask why do u guys pre buff everything before even pull? doesnt that waste secs per buff..like lets use A1S for example..even correctly lined up wit tanks pull..you running up during buffs stilll wastes the time pressing buttons n moving..but im on ps4 so i dont know if its easier for pc to do that.
- also, since alot of people agree that weakest buff first towards strongest buff for maximum WF output, then why isnt hot shot first? since its only 5% and it also lasts the longest, so you will have full effect till end, only diff is non buffed HS, but you can add in another GCD, even split or able to complete the 2nd slug or clean shot in time.
- also i dont know too much about turret auto attacks, but do they attack when you attack or when tank pulls? if it only atacks what you attack then your first move should always be a attack.
- regarding to that too, do people have GB on in beginning? if so, i dont get why, especiailly if your just using buffs, wouldn't it be better to let yourself do 1-2 AA dmg during buffing time than to start off with GB.
-since thats quite a bit of questions..i dont know if this would be a prefered starter since i dont know much of the question mechanics.
but.. [ GB OFF, tank pulls, hot shot, buffs(during this time your turret and you AA will be attacking too if the turret question was when you attack), as your buffs are going off, your AA will increase too up till the point you need to do lead shot, then GB b4 LS --> standard rotation] based on my own testings on ps4, it seems this way im able to fit my entire rotation w/ buffs ending like literally last shot..but if i had GB / hotshot..then it wouldnt get to the last slug or clean..but could also be a latency? i dunno..i have a macro to swap me to a completely new set jus for rotation going with everything thing in order... (pretty much like pressing 1-10 on controller)

TLDR shorter questions
#1 - best secondary stat between crit,det,SS
#2 - Why prebuff before even hitting the boss?
#3 - GB in beginning or during buffing stage?
#4 - Why not use hotshot first since its longest buff duration?
#5 - do turrets attack only when you attack or when tank engages?
