Had potential, but then the energy system was in there just so you can develop FOMO (fear of missing out) along with a daily routine of playing to avoid lowing progress, this sucks when you have free can blast in a few hours but have "limited lives", all of this has the sole purpose of creating a routine/making the user pay for when they want to grind. In summary: sadly they missed the opportunity to have a nice game.

good game destroyed by greediness. game is fantastic good graphics u can make alot of builds , good story , its all good  until the p2w starts everything has an alternative with real money alot of subscriptions and premium pass and they try to push u by making the levels requires more power than u have but if u managed to make a good build to withstand the levels that got hard guess what they did they put a f timer  in the story mode and in all the content  of the game ,u will face all of them have timers i managed to make a build with good damage and heal and i can easily finish the level but with more time but i can't and the problem with these stupid games u don't even know what to buy with real money to be good , they really have a pay wall to evey mechanic like tickets to events and arena(which is not a real time pvp btw) and some essential content to upgrade your gear, premium pass, cards , enhance materials, diamond and gold , pets .

I consider myself a veteran since I played this game a lot and I want to say that this game became my daily game. It's a game who respects your time even tho there are a few bad things here and there. You can do your daily quests in like 3-4 mins while you drink your coffee in the morning, you can advance in champaign while you waiting for somebody, heck, you can even spend half day doing stuff. You can be casual today and hardcore tomorrow, you can play it without feeling bad because you just went on like 10 mins yesterday. The only things that are forcing you a bit to play more than you want, are the events but even so, they are not so time consuming. You may find this game boring but in my situation, it became part of my life and I can fit this game everywhere in my life when I'm bored or I just want to waste time. I'm not a p2w player btw and the developers are great, they offer you tons of crystals and codes. 10/10
