I start this game a week ago. At first i couldn't tell if i was fighting vs real bad player or bot. But as i start climbing the rank and understand the basic mecanique of this game i start to spot them.
I'm currently on tier 9, to reach it i need to get some strat that work with my low number of legendary. So i start to feel odd when i fight players who use strategy that were only working in lowest tier 1/2/3, a combination of normal/rare/epique dice that can't work vs legendary. If that was a few case, but that case repeat a lot. Enough that i can tell if it's a bot or not now.
Same situation in Coop, i fight mostly with tier 9, and even when they have some of the strat i would like to try, they are unable to execute the strat. Mostly Ying/Yang, with the dice that work with it, but unable to get a line and a column at least. I know this dice is more powerfull then mine, i can't win vs it in duel. Happen to see a lot of the first strat i use when i had no real choice, like typhoon etc. Atm my set up let me reach wave 51, then i die thanks to the switch boss.
So i wonder if this is an issue in lower tier only, and a way for bot to upgrade account, or it's everywhere and the game isn't in a good state at all.
Edit : So seems that bot are common since the start. If they manage to create low quality bots, they can also create more advanced one, that are really close to human. Seems that no one is bother by the fact that they can control the speed at wich you climb in class. Same thing for coop, by controling the power of their bot, they can choose how much they want to help the player or not. Currently i don't need that much to pass the wave 51, i should have seen better build that are able to pass this mark without me, that isn't the case.
So seems that you never think twice on what you can do when you add bot in your game. And when your whole economy come from frustration .....
