I've played few days and realized that heroes balance is bad. Most of the time I play by Queen Archer, and any another hero kill her 1vs1.
One time I had lvl5 Queen Archer vs lvl3 Barbarian King, mine has 90٪ hp, enemy has 20% hp. And I loose.
And that happens frequently.
Time for casting her spell is too long, and while she do that, she receives 2 hits.
Also it's quite strange that Melee heroes and minies have bigger damage and bigger HP. So for range minies only one advantage is few seconds for shooting from afar . But arena not so big, plus have jump pad.
I hope they rebalance Melee and Range heroes and minies.
