But do you really like SC in dominions2 ?

[Oversway]

The point about having life drain still stands, even if you remove trampling from the equation.

I have absolutely no problems with SCs as they currently stand, as they are vital to prevent the game from devolving into a zerg rush of "whoever has the most troops wins".

I'd say that SCs are not the only thing to prevent such a problem. Area effect spells, battle field summons, trample, artillary spells, etc. prevent this as well.
