That would be my use for them, but only 25 turns for each not worth imo, it's annoying to recast the infusions.
That's my problem with it as well. Especially since the infusion slots don't have a hotkey. It's easier for me to just bump up to tier 2 or 3 and burn mana pots instead. The exception would be the jump from nightmare -> hell but even using infusions, I can't quite 1 shot on hell, so it doesn't matter.
