If you don't like the idea of a veggie, then do a integ+ff+meat+hack+mantis+buffs (with adren for person with one buff)+healing ring run. Depending on the whether you use powerups most of the crew can ditch healing rings, and feel free to add a knife sharpen.
Lol, sorry I d/c before you got to see how the veggie concept worked.
Usually, someone doesn't bring meat and brings at least 2 passives. Integ + FF is usually a good combo due to stam regen and the increased accuracy + dodge. I normally do 2 passives+2 attacks+1 heal+3 ring slots open for ring assignment. I only do this for yellow maze though, and certainly not for GR due to the damages of bats and such.
Going veggie also increases your shadow orb/loot drop and I would recommend doing this method with a cl 11.4+. Any lower, and you might have some trouble staying alive. Also, all my rings are leveled, so going veggie doesn't really affect my CL overall, since CL can affect the scalability of some buffs and such.
There are some more details behind an all veggie crew but this is just general info about being veggie from my perspective. (Also did an experiment with an all veggie crew and cc is definitely important ;o)
