Excellent video! You make some fine points about the reward changes.
For me, there are still some additional unknowns that the new reward system may have on the bots. 1.) Some bots don't rent everyday. Particularly in silver, there are a lot of them that rent every 4-5 days, play many, many matches [presumably to pay for rented cards], and take advantage of the two daily chests they can earn [presumably this is the bot's profit]. It's been stated that the new reward system will emphasize daily play thus making this bot strategy less, if not un-, profitable. 2.) There is a question about just how "smart" the bots are. You noted that not all bots would be able to rent a set of CL cards. Will they be smart enough to rent cards outside the starter set and use them? Renting different, potentially a "random" set everyday, of cards & combinations may be problematic for their algorithms at least initially. 3.) Tying reward chest to ECR may change the way in which bots play. It might not be beneficial to play 200+ games a day anymore. The best return might only be 30 games a day. This is probably the biggest question I have for new rewards. Will it affect the volume bot game play?
