First thing is this on the magic and attack page. Resting units are unavailable to send out on attacks. > Sayjins post resting units and available units like wizards?
Second thing treat it like the rest time like Wizards, except 1/4 of train ATC/TC train rate rest time. ATC Train 100 SB per tick, they rest at 25 SB per tick.
As far as unit losses go, maybe something like this, so it still has the high loss potential but it's not as common and unless you have the luck of @Sayjins you shouldn't see it often.

Wouldn't mind seeing that for gate either. Loved the battles where I lost more in the gate than I did in the attack.
