I have a couple of suggestions to make generals easier to manage.
First, now even if you are just doing adventures requiring elite units all the generals default to the normal troops. I would like to see either generals automatically default to the elite troops once you hit lvl 60 or have an option to set them to default to the elite troop panel.
Also, as we keep getting more generals it is becoming harder, if not impossible for them to have space on your island. It would be so nice to be able to have carriers (like aircraft carriers) or something similar that can be located maybe below our island in this area that all the generals can land and be sent from (maybe 25 generals per carrier). You could make content that would enable players to earn these carriers if they wish or need to have more than 25.
