The host would pick everything, the bots would use the same loadout the host has for that character, like if the host has a level 7 JD the bot would use a level 7 JD with whatever cards the host has equipped
A jackbot I’ll admit idk how they’d make it useful, just make it burn weapons in between rounds if theres a forge, use its ult on heavies only, and make it heal asap when teammates are down
Engineers would pretty much be like Gears 3 horde, they put set stuff in certain areas and upgrade/repair as they see fit during downtime (although if this ever gets added they should have an option for the player to tell what to build and upgrade, the bot just decides where)
The weapon lockers you got me so those wouldnt be as useful in these games (aside from having a bit engineer just build a couple and upgrade them for you)
I dont think it would be hard to give them an option to use the GL rockets (if it’s not possible already)
On a bonus note they could bring back the command feature from the Gears 1 campaign for this and like actually make it work. Tell the bots to stay within a set area and what not. Frankly though I dont think it would be this popular for TC to go this in depth with it so this part is just a pipe dream.
On a bonus bonus note I hope that if by some chance they do this that the host can give the bots a character skin, like a full gilded squad or other things
