Best Trio That Doesn't Use Enchanter

[Toxigen]

No enchanters allowed because lets face it they're way too powerful.

I'll start:

Necro / Shaman / Monk

All iksar, start together at level 1, bigly RP lizardbros, can do well with low budget twinking or self-found, great off-meta Kunark leveling route.

There you go DSM, you finally got your Shaman in a "Best Group" hypothetical.
