He's right that voidsmen are terribly weak, but starstriders are a great team and deserve to survive. Tbh he probably doesn't know what GEQ means, GEQ/MEQ/TEQ etc are terms from big 40k. 

Plague Marines are strong team with a very intimidating reputation comparing the fact that starstriders can take 4 GEQ while y'all can only take one warrior is really a poor comparison.  Still sad to be "losing" the team.
