that would be a good idea

but i have been noticing a lot more often that the teams end up looking alike either way by that I mean each team has a UB and Reg and Rook. Or 2 out or the 3 being the same

"It also has balance implications, what if my team chooses all 4 generals, we would be healing maniacs against 4 poor assasins." dydx

no as stated in the titel , each side can choose form all demigods ... example : unclean beast can be played once on light and once on dark side.

"Forcing decisions like this sounds nice but what if you're the person always connecting late and can't choose to play your favourite DG because of it. " dydx

it would be just for custom games, so it up to the person to join if they want to stay or not .. in the end the host of the game can define the rules.

This will never happen, nor should it, I would like to see some things implemented to prevent stacking from being too powerful.   1 common example I hear is 5x snipe, then stack all your mines up!  Obviously theres ways to counter this, everyone stack early health items early for example, but generally it'd be very hard for a non organised team to contend with.

Instead they should implement minor changes to prevent stacking from being so powerful.  For example, getting sniped could add a 5 second buff to the target reducing the next snipes damage by 25%, this effect should NOT refresh from a 2nd snipe, just cause the 2nd/3rd/4th/5th snipes to do slightly less damage if they are all used at the same exact time.

But honestly nothing really has to be done, if ppl want to try and stack things like, say 5 tower rooks, then other players will just find ways to counter these teams.  Assuming something isn't completely OP.
