So player have time to focus on combat and enjoy the H animations.
I would love if they bring back idle room for units to stand like in monster black market. For me , It's hard to keep track of units with projectR system , new born unit keep add up and at some point i lost track of what unit i want to use after i get more than 30 female and 100 monster.
Bud the combat doesn't happen that often. and it isn't a hassle if you organise properly.
(I reserve Page One for the left and Page Two for the right side (slot one is the Deployed Left army, with slots 2-4 holding the reserve troops and slot 5 for deployed right side with slots 6-8 for their reserve)
As for keeping track, do you realise there is are sorting/filtering functions in each list?... keeping track of the newborns is easy once you change it to "show only undeployed" (not like you ever need to touch them again once you've dropped them on a tit).
I also use the "lock" function a lot with the "show only undeployed & unlocked" filter function (the lock is the little padlock symbol in the corner of each monster tile, locking all the "trash" monsters makes them vanish from the list temporarily while I look for the quality characters that I'm going to use for breeding... Rinse/Repeat for the "Quality Troops" to be used for Base Defense leaving the Dross for Cannon Fodder/Sacrifices.
Additional Tip; you don't need to "drag/drop" monsters/slaves out of the breeding area/armies, right clicking sends them back to the general pool.
