High level Hideouts have a lot of cross server opponents. I propose a room that gives additional attack bots when fighting cross server hideout targets.
Say my opponent requires 30 attack bots to guarantee a win.
Level 1 of the new room would make it so I use 29 real attack bots and 1 bonus attack bot for that same win.
Level 2 of the new room would make it so I use 28 real attack bots and 2 bonus attack bots for that same win.
Level 30 of the new room would make it so I use 1 real attack bot and 29 bonus attack bots for that same win.
Since cross servers hideout fights do not drain defense o bots and do not actually take opponents resources. This would allow progression with no imbalance to opponents.
I would think this room would be better if accessed at level 30 hideout base since lower level hideout bases likely would not have cross server battles.
This would allow high level players an easier time to do 20 hideout fights on a regular basis since most fights without this type of room take 20-54 bots to beat 1 target which can be painful.
