I made an account to respond to the clear lack of patterned understanding to what role Jacque plays.
1) Yes, Jacque is high dps, low space taking hero. Therefore, it is almost a must in every army because it's too effect on a dps increase / space taken perspective
2) No, Jacque is not over-powered when it comes to late game. A simple way to understand this is to test the relative damage of a level 30, 50 might Jacque in a 20k vs 20k army battle, and then compare it to a 40k to 40k army battle, 60k to 60k and 100k to 100k, so on so forth. It is not hard to realize that Jacque's power and damage is independent from the army in which he fights in. So yes, when you link images of a level 5 silver armies fighting another level 5 silver army, a high power jacque (even if it's not level 30 might 50) is overpowered because at low level, jacque is a lot stronger than the army he fights in.
However, the way scaling works in this game is that each level the troop gain, you gain approximately 30 percent damage and 30 percent hp, based off the power of previous level. Therefore, it's literally an exponential growth of power for troops. Whereas, hero power is gained likely much more linearly (each level increase of might gain 0.5% damage, each level of double gun gains a flat amount of damage multiplied by might multiplier - overall very linear and growth is limited and slow).
Therefore, when you have a level 30, 50 might jacque in a level 7 army, he's OP, in a level 10 army, he's not so OP anymore and die very quickly to fully buffed level 10 gold archers or knight. At late game when troops are level 12 or 13, jacque isn't nearly as good.
On the contrary, take a hero like Avalon for example, He buffs all humanoid hp by a flat percentage multiplied by might, and then buff hp and damage of archer by a flat percentage multiplied by might. At level 7 armies, avalon is pretty bad because a 2000 hp, 5k damage archer only gains a portion (for the sake of argument say it adds 30 percent damage and 50 percent hp total), thus gains 1000 hp, 1500 damage for each archer
Take this same scenario to level 10 archer, where they have 6k hp and 12k damage, you gain 3k hp and 3600 damage per archer. Hp and Damage of individual unit added together is the effective damage and effective hp of the army. Therefore, Avalon has a lot less influence for a small weak army than a big strong army.
Jacque on the other hand, is a flat contributor. So, Yes Jacque is OP early, but weak late. and Avalon when compared to Jacque, is infinitely better late.
Think about the entire game mechanism as a patterned and interconnected behavior, not from the perspective of a single point in time and you can understand this game a lot better.
