It'd be different if I was chained to the computer playing without sleeping or eating til the game is completed. I never had a problem with something fun I already paid for lasting longer, especially if I can choose my pace and time to consume those hours of fun. I think it's matter of whether you're having fun with it or not. To me it is by far the toughest encounter in the whole game, as it took me a good amount tries to get it down while for example, I got the Sigilmaster down on the first try, and the others within the first five attempts, give or take, which were mostly to get familiar with their mechanics and combat phases. It makes it into a highly strategical and at times frustrating fight. In the end you learn to manipulate a bit the turn order to try to guarantee that all your members can move in between the time the bombs are laid out and the time they detonate, together with some widespread fanning out so with luck some of the members won't have to move at all makes the fight doable, but it's never a guarantee that it will work. While in real-time he spreads the bombs and they detonate in a certain time and all you have to do is pause and move all your characters simultaneously out of the danger, in TB those bombs sometimes are spred out and detonated before some of your members actually had a chance to act in between, leading to inevitable deaths, that in a tough and long fight as it is, ends up beating you through attrition, because your characters hit final death after 3 'knockouts' and can't be brought back anymore.

In Path of the Damned at least, those bombs one-shot your party members, and here's the tricky part. In general, they are about the same I'd say, but I found Dorudugan (The giant golem) is harder in TB because of his bomb detonation mechanic.
