I find the bots are either too hard or too easy to beat. They do require a lot of fine tuning to get right. As you mention they have all the cards which I for one do not. I find in champion they use poison burst as much as possible. Which in itself can be easy to counter, especially when they put it on random units that don't get hit. I think the root of the problem is we need more players and this is noticed more and more towards the top end. Hopefully the player base is increasing and over time we can switch the liquidity bots off or reduce them at least.
