Currently there's a definite need to be able to get rid of your lower tier troops. I think the research tree should be updated to include the ability to turn unwanted troops into dragon food for a gold cost. There will be different levels which are unlocked depending on what tier troops you have unlocked. And there will be the ability to improve troop to dragon food ratio in a research tree also.
Lol 😂😹 I just suicide the unwanted ones, but wouldn't mind being able to turn them into better troops for a price.
Nope, you get no xp for PvP actions...but totally for PvE...but they aren't at risk during PvE...but node gathering... You get xp there, AND they're at risk. Haha, just find finding a way for them to be xp fodder, lol
