easy way to add an advanced co-op vs AI
 

Current bots are fine

but to add an advanced or hard mode

why not just tweak the items that bots buy quicker.

20 min of work for a extra mode -> ?? -> profit

Or have them buy/place wards, have more active map awareness, actually try to take baron, better item builds, and a jungler and top lane depending on their team composition. Maybe even throw in some intentional counter picking by computer based on the champions people have chosen.

See, that takes work. it would work, but it takes works

I'm talking about a easier way to make a hard mode

The champs currently are decent enough, If they speed up the item buying buy like 1 or 2 minutes then it would make a challenging mode but without modifying the current AI.

Have a bot buy RoA at 16 min mark, finish final item builds by 35 min mark, ability to sell Dorian items.

OR

Make it so that the bots naturally have the same amount of Advanced/Legendary item as the Co-op team.
