For lower levels (esp. farming 1-10), it's easy enough and Pomanders of Strength are plentiful enough that you can eat one just to clear the dungeon a little faster. People still save them to shave seconds off the boss rather than minutes off the dungeon, for some reason. A full run takes just over 10 minutes at a medium-fast pace, and the strength and haste buffs last for seven minutes. It's honestly a waste to not use them.
