It's an interesting concept as a counterbalance to an OP unit situation.You definitely CAN bribe units (might be a feature that must be turned ON, dunno), but maybe not ALL of them either.
And my suggestion is more towards "how to CATCH the annoying War Trolls that demolish my armies" and not so much just to catch them for (not so) free.
I never play that way anyways (I actually prefer political warfare in the first place, as opposed to endless wars that last forever and ruin the FUN of turn-based playing).
Just thought it might be a viable solution to "these FRACKERS keep eating my armies, no matter what I do", ya know.
Never mind, I guess.
