Downloaded last night, got young Tiki right off the tutorial who is a very strong character and the one I actually was hoping to get eventually in the game.

Have her at lvl22 and then all my starters 15+, wiped the floor in Arena and I'm at story 8 but just running through them all again on hard mode for orbs completion bonus

Realized the starters were tin and not silver so absolute trash but Tiki been carrying me so I don't mind

PvP seems pretty stacked if you have 5-star(s), won 10 in a row using Tiki and the tin rated heroes you get when starting .. when she is attacked she goes dragon form and takes 0 damage from any unit that isn't 4/5-star and one shots all units basically
