For a guy that uses up to 2 regular units (dependent on attrition) in GBg along with rogues (as myself), I had originally thought the game had a bug when the healthy rogues were before the wounded units. I usually exchange the regular units once they get to about 1-3 bars of health left (losing them would not be a problem either as I have more) before I put in fresh new ones; the rogues I do change once they hit that point or are dead (again, I have a lot of those as well).
Although, I do hope on some real changes like:
• Formation Presets: A feature that you can save up to 1-3 troop formations to be called upon when the button is clicked (browser version) or tapped (mobile version). This will load 100% healthy troops. For instance, if you have a Hover Tank in slot 1 and seven rogues in slots 2-8, it will call up that Hover Tank in slot 1 and the rogues in slots 2-8, all at 100% health (and if in army troop inventory). If there is no unit that is 100%, a notice will tell the player that no unit is available to be deployed and will leave it to the player's discretion in using wounded troops instead. With this QOL in place, it will give players an edge against those that cheat by using a bot or script to swap out troops with ease, which could be helpful in GE, PVB, GBg, and a few places where battles are essential.
• Main Army Screen (Interface): It should show the list of healthy troops available to be placed in formation via manual or preset means; no injured or wounded troops. When a player clicks by type (Fast, Light, Heavy, Artillery, or Range), it would show the injured/wounded troops along with the healthy troops.
• Defensive Troops: I liked the old system where defense and attacking troops are in separate formations. Now, with the introduction of the PVB Arena, those troops designated for defense are marked with yellow or blue markings which is always placed in front of the regular ready troops for deployment (aka attacking selection). I quit the PVB for many reasons. Those defensive troops should be placed in a building (either townhall or a new building called "guard shack" or something similar) where we can access to see what defensive troops we have from city defense and PVB (for those who still participate). Or, we can have tabbed windows like the tavern for the army management screen where the default view will always be on "attack". Then again, I am still waiting on Inno to fix the bug on the tavern where it opens to the ad-based boosts when we click on it instead of the tavern room where we can collect on the seats of our friends (YES, it's a bug if it goes into the ad-based boosts instead of what players wanted in the majority which is the tavern room).
So, it's a meh from me about this that I would have to get used to until some real changes do happen.
