sometimes trying to do things faster is like trying too hard. like you can clear a dungeon in 15 minutes while you can actually enjoy the game. but if you push yourself at your limit you can do it in 10 minutes but you have to concentrate yourself for the entire 10 minutes in a low level dungeon, it's not a good way of playing for everyone.

I myself can do speedrun but sometimes I'd rather do it 5 minutes slower while I can relax in the dungeon. 5 minutes don't mean anything. ppl are ok with themselves AFKing for hours but they'll get mad because of their party members make their dungeon run take 5 mins longer. doesn't make sense.

the best way is... make a premade party if you want to do speedrun.
