need some help with a 4 man group setup

hey exiles

if the group play will be the same as it actually is, we wanna do a 4 man group in the next league.
at the moment im only experienced in a 2 man group (mostly ts deadeye + aurabot) and thats why i need your help.

in my mind the setup would be something like:

- full mf map clear (guess ts deadeye would actual be the best)

- a boss killer which would work at league start with cheap gear (like glacial cascade miner)

- scion aurabot (necro and guardian notes)

- occultist cursebot


guess the most important thing will be the synergy between our supporters.
i hope someone can give me a few tips or have some ideas or maybe both.

thanks for your time and good loot exiles
