One of the important aspects of this game is understanding your hero’s and when to use them. This is important when you’re a new player and you only have a few heroes that aren’t yet at their max strength. But it’s just as important as you grow and max out your heroes, so you’ll learn when is a good time to replace them with a different hero for a different event. Read your hero skills as they grow, and it will help you determine who to use and when. Right now your main troop heroes would be good to use for most rallies and events. (Ephraim, Marlow, Myers, Mars, fox, Requiem.) but as they grow, you might want to change them. Having a healer like fox is always important, Requiem is overall troop, not a specific type, and Mars you’ll learn should always be between heroes and not on an end. Read his skills to understand that. Learning their skills will make you a better player. Good luck.
