Disclaimer :
All of my Builds are supposed to be new player friendly who are looking for a cheap and less grindy build to go through the entirety of star chart and sorties with ease these are in no way end game or anything builds
All of these builds follow the current meta

Potatoe becomes a necessity if you are looking for a decent build, you do not need to Potatoe everything you come across best is to just keep the weapons, warframes, etc you like using and try to mod them good enough in accordance to your playstyle and need

Base stat matters a lot for any weapon, High Crit chance and Crit multi with good range is always a good thing, for Damage High slash and one innate element (If given chance go for innate toxin damage)

No, you don't need to follow the build as shown, mix and match based on your need
