I like how these power rankings are similar to the ones on my blog. Although I haven't done the blog for thee last 3 units, I'm sure they would be similar.
I'm thinking the Gnids are getting a little too much credit, as guys like Q10 or Q9 will laugh at them, and now even the elf wizards with Haduc will be even more of a threat to them. I'm not seeing how they are a B+ unit yet, sorry
