I played through MM7 again last week. That game got too easy once you got a blaster. Casting Day of the Gods and Hour of Power/Haste with a blaster equiped would result in a zero recovery time for whoever had the blaster. However fast your keyboard was set to repeat, you could fire. You could literally go to the Land of Titans, get in front of a huge group of Storm Titans and Red Dragons for about 10 seconds and they'd all just fall.
It's also kind of interesting to use this against a Lich King, because they have a shared damage effect so when you are shooting the Lich, you can watch your health bar just plummet.
Best characters in the game: Monks
Never have to get armor or weapons repaired, had HUGE armor class, especially at Dodging grandmaster when you can add leather armor, and Unarmed at grandmaster was like cheating... You get a decent amulet that boosts unarmed 15, and get their skill up around 20, and there's just nothing that's going to hit them except magic.
Plus you can have them cast spells, I never bothered, because I would generally have a Cleric too, but still... crazy.
Worst part of the game: Not having someone be able to cast grandmaster level Protection from Magic. Against Toberti/Robert the Wise, it was way too hard. Death effects are lame, and he could use them so fast that without PfM, it could take several tries to kill him.
