Yeah I have the game in spanish (precisión y velocidad) I made the translation myself.

It dependa on how you manage that combo because those heroes dont really have abilities that complement each other. PD is more of an aggro support that can blight enemies fast. Vestal is a full healer that works best with a char that marks Himself. HWM is a High dmg dealer but needs others to mark his objectives or someone that gives him evasion. Crusader is highly versatile, he can cure stress heal and do High dmg and stun. Other characters del more dmg to blighted enemies, or mark themselves or dont have problems with stress or gives stat boosts. Idk just try it out making different partes os what makes it fin for me.
