thank you Ember,
but honestly, free stamina on trials and time rifts doesn't help too much,
because you spent stamina, it give your team exp, valuable items, and this is on your daily quest too.
Players main goal is leveling their team level ASAP and upgrading their heroes.
so with or without stamina, it is already on players duty list.
what the players need here is stamina and experiences for heroes!
a lot of obtainable heroes but they can't use it.
they must sacrifice their main heroes to try their new heroes. and without their main heroes, they can't going any further of this game!
and for stamina, you need to lowering the interval on stamina recharges.
all players are lack of stamina, everyday just waiting daily free stamina, and then spent them on raid 10 (especially high level players who stuck on next chapter because team level requirement), then waiting again for next free stamina.
what is the meaning of installing this game on your phone if you can't doing anything beside of waiting and waiting?
you can lowering down to 3-4 minutes per stamina, so your players can do more with your games.
sorry for my bad english and grammar,
your game is gaining worldwide fans, so you need to hear and caring your fans.
Thanks
