Also if you look at the strategy section if the AoC official discord you will see some experiments done. Me and. My friends on the ptr with the jacques free hero boxes.
I spent 1200 linari and I got a level 18 jacques with 20 might with no items equipped. My one friend got to lv 24 with 3000 linari and solo'd tactics school up to 2-14. Without any supporting troops. Literally just jacques.
That's one hero vs a dozen or more silver 8 legions and he wins. That is not balanced I'm sorry. If a hero can literally solo an army past the mid game that isn't fair. And this is only a 40 might jacques if we spent 100$ 14,000 linari you would easily have a capped jacques day 1 and boom you win gg server over.
