Wedge with swarm
garvin
rookiesx2
Two separate powerful groups to hopefully spread out opponents
Naturally Wedge swarms rookie1 and Garvin gives focus to Rookie 2 giving two potent groups. Also a chance for initiative in which case swarm will provide an even greater advantage.
Or:
Luke with R2D2
Garvin
Rookiesx2
A much more defensive build to hopefully last long enough to do its damage and wear down opponents.
Just curious which you would pick and why?
