What? their paladins only take 1 extra hit from halbs like the Frankish one and you totally forgot about the lack of husbandry which that alone balances them out. and still no understand that why are they so strong but Frankish one is fine? both are pretty strong at melee combats (And Franks have much stronger bonuses to spam them)
And still kill halbs in 4 hits even with all 4 relics, was OP when they reached up to 23 attack which enabled them to kill in 3 hits halbs, without mentioning that is the only brute force bonus that they can use for offensive purposes. And if Leitis is so OP FE could adressed it 3-4 patches ago like the Goths at their moment, but no both Teutons and Lithuanians are fine.
To add that while you think Lithuanians are OP there are even a post asking help as them vs massed halbs: What can Lithuanians do against massed Halberdiers?
