After further review, I am tending towards agreeing with Tuidjy. I would rank this version of Hoburgs somewhere around the vicinity of Helheim strength for the early game, providing of course that you optimize it for the blitz. Pretty strong compared to the vanilla game. Have no idea how it compares with the other mod nations though.

Some possible counters:

Early game counters: Trampling units, star fires, air shield bless, tangle vines

Mid game counters: Arrow fend

Late game counters: with only 6 hps, pretty much any type of battlefield wide damage will wipe the whole legion off. Foul vapors, Fire storm, poison cloud, fire cloud, etc. There are a few map spells that should be able to wipe off entire armies too.
