Enchanter>Counter minstrel?

So I've decided to (re)make my minstrel but I had a problem: I wanted to buff as if I were support but don't want to be useless in a fight. Since I like solving my own problems I searched for a build that could serve as support and offense which was *Drumroll* the counter build! I'm planning to copy the enchanter counter build (to the best of my abilities) and become minstrel 200+ and live that iruna life BUT idk how often autoskill will proc so i'm not sure if I'll actually kill anything.  I'm well aware I'm not solving this alone haha.

So my questions are (Thank Almas he's done typing)

Which equips should I use? 

Will my build actually have offensive ability? Not looking to solo the gods just want some self defense (No pepper spray in iruna)

Should I become minstrel later?

Am I Wasting my time? Had to be asked

equips I had in mind for autoskill set:

Resty Rod/Gerust and magic sword (if needed) idk which
Dragon mail and DPR w/sofys
Spin shield and Ensis shield (havent decided xtal)
Lotus seeds or mq specials w/sofys 

ANY feedback is appreciated you wont hurt my feelings...much
