[Illuminated One]

Did anyone think about the possibility of having to attack Hinnom with Marverni? You have enough armor for 2 of your druids, the rest and all your communion slaves go unarmored.
Now you know or suppose that Hinnom has Earthquake scripted twice.
Do you
a) Cast Ghostrider (or do whatever) to make sure your mages are not hit by the earthquakes
b) Send in your mages to find swift dead

Now this is a perfectly viable game situation that should crop up in such or another form in many games.

I have never seen the other thing crop up, but I can believe it happens in lategame madness. But as I said before if you blame the brokenness of late game on things that work perfectly fine during the normal game (which is what interests normal and especially noob players - the real bordercase is the lategame) you will only reduce the normal game without making anyone content with late game.
