Absolutely pay to win which is a damn shame bcs its beautiful orherwise. It doesnt deserve your attention. 
+Fun combat
-Horrible Hero Balancing
-Horrible Gacha with equally wretchid rates
+Decent music
-Extremely Boring and repetetive modes of play and daily loop
Aggresively pay to win. RIGHT off the bat, heroes locked behind paywalls.... Check leaderboards.... Familiar faces.... Uninstall
(Literally two of the best heroes are locked behind a two packages, between 50 and 70 dollars if i remember correctly)
And of course the **** gacha comes with extremely slowly earned premium currency and tickets with tweaked rates so you pull trash more often.. wait whats that? You must exchange the currency for tickets before you can pull?

**** EVERY WESTERN PUBLISHER WHO DOES **** LIKE THIS.

go check native version of game like 2 years ahead in updates, happy and appreciative playerbase and communities , and no paywalled heroes or stupid dupe system.

Our version you need dupes from lv ONE for BASIC ****ing development. Dont do it.
