Well it kind of is since if you have map hack, you can kill anderial, Meph, and summoner all within 90 seconds. You can’t know which way summoner is. You can’t know where the stairway is on catacombs 3. And half the time meph’s room wraps all the way around to the back of where you came in on the waypoint and it takes a while to figure that out.
It basically means that without maphack, you’re looking at 3- 5 times longer. That means maphack is 3-5x more GG loot. So yeah, it matters.
