The AL is one of my Favorite variants of the Centurion, & clearly my L1 favorite.
But as I stated, I was trying to keep the total #'s down to the "best" factor.
Even if "best" was at just a single role
And as mentioned, the Hunchie was really an honorable mention pick for being the only mass produced AC20 option, and doing what it does, "Urban Defense" pretty well for it.
Black Jack & Whitworth are both mechs I happen to like too, but they didn't scream "Best" over all, or even in a niche, like the Assassin would with "Recon"
