Wondering what impact the possibility of making legendary 5* troops available in the game ; this might evolve the game a little bit, for example the 5* troops of each element would have combined stat features of the current epic troops:
Att, Def, health, critical & mana speed.
It’s maximum level would be around level 50 at barrack level 15.
This would also evolve event contests further as
Rare events will now be limited to 3* troops instead of the current 2*,
Epic event will be limited to 4* troops instead of 3*, likewise legendary event will now accommodate the 5* troops.
Summon gates would also evolve to include legendary troops.,
