I had done some speed testing and this is what I got from this daft of a feature.
Out of 150 fights (sample size):
• 30 times I would get a defeat screen because somehow the formation had all rogues instead of that one unit. This happens when I was speed clearing the formation and the flesh wound of a regular unit was taken out as well; and I rapid click in all the rogues to get the fight going.
• 25 times I would put in a unit that was supposed to be in formation with a unit that was supposed to be removed while replacing all the rogues. I didn't lose the battle most of the time but I did lose rogues because of the unit that was weak to the army I was facing.
• The other fights, I had to slow down so I can look to see which units I need to replace (rogue or regular).
Whoever said this was quicker, I would love to take you out back with a very thick phone book
The only way I can have my sanity (and eyes) saved is if Inno comes up with the "preset" option.
