Well like I mentioned before AGOK's has 30+ monsters (the + is for the special monsters I add and subtract).

now the prob is there's 3 races, each with an option of recruiting 10 diff monsters...

now how my attack system works is... the defender puts his men at the 5 different parts of the castle...
like so

front
back
left side
right side
center

and you can only select 5 monster slots to guard, so you can put 1 group of monsters in one slot in each one of these places or put 5 monster groups in one slot (preferably the center lets say, if you didn't build up your castle defenses)

so you get the idea

then the attacker gets 5 waves and you select which wave goes where, so you could have all 5 waves attack the front of the castle (in the end going for the center since the center is where the town leader is).

so that's the basics of my system

do you think it'll work or should I add more slots for defense or take more away from attackers?
