Welcome dear steemians, today I'm going to mention some issues about the game that called my attention in this league, the bots.
I have played since the first season to this game and analised the cards in a serie of articles, in my experience I have played against bots since the beggining of the game and some of the changes done where focused to avoid the bot exploit with the intention of amass in a let's say "inapropiate way" a lot of cards for free, which might be soft words for describe this phenomena.
This last season was an example of that, the format changed in every match, the mana max also and the splinters that where selectable, the idea was to solve the problem that using a simple bot with the same team in every match you could obtain a big amount of cards. The existence of bots it isn't a big problem when they're in inferior leagues. The amount of cards that they were capable to obtain wasn't so big, but now we are seeing teams of lvl1 to 3 in Champions league which is absurd.
It's not like I complaining about them, they're an easy win for everyone with a regular team but are a problem to solve for the developers because they low the card prices as the reward cards are being claimed at a higher rate. They can be necesary to have matches available in some levels but if they are being used with other purposes that could harm the game.
The changes of this season have been nicely done by 
Cheers to all and have nice holidays.
