Sorry for critiquing, but your mistake was attacking Rome far too soon, but then again whenever I play Total War I somehow manage to piss off basically everyone on the damn map every single time, so it might not be my place to talk.
My own example is actually several moments in Dragon Age: Origins, and they all revolve around 2 spells, Chain Lightning, and Curse of Mortality. Now Chain Lightning is for all intents and purposes the DA:O equivalent of "Rock Fall, Everyone Dies" the only effective counter to it is to know ahead of time which specific encounters involve enemies with the spell, and then bum rush those everyone else stabs/shoots you in the back. At least this spell has a slight balancing out since you also get to possess the spell yourself and it's just as effective against enemies.
Curse of Mortality on the other hand is redundant to the point of uselessness in a player's arsenal but WILL kill one of your party members if used by an enemy. It inflicts large amounts of damage over time, while simultaneously completely taking away your ability to heal (Something enemies in this game almost never do anyway, making it totally redundant to similar spells like Crushing Prison). Worst part is about 70% of the time this spell gets cast on the very last party member left standing just to pour some salt into the wound.

The really weird part about the frustrating sections of DA:O is that the difficult gulf between Normal Difficulty and 'Casual' Difficulty is cosmic. I bumped the game from Normal to Casual during one particularly ball-busting section and I could have literally won the battle with my eyes closed. It's not meant for new or 'casual' gamers, it's meant for gamers that just came out of extensive brain surgery and can only use 2 fingers.
