i have noticed the 2 KOE runs re Short and Long one, (Short being the one with the rock elemental heart and blizzie (this chain has less kill 10 and poke them with a stick after).
im engineer (MiRage) 56k GS and the longer run takes me bout, 45min max, and the shorter like 35min max, these times re about 10min too long coz i chat alot when i come in to game and Koe is first thing i do.
also these times i "recorded" when i was alot lower geared, now for example i can pull 19/20 of the league mobs in 1 pull, (damn i died with 20, 2014% wound complexity

)
But yeh, been also thinkin how long it takes others to do this aswell, nice post
Forgot to mention, it rly aint worht the gold, 1800 in 30min or so, i once farmed full 50 k marks, too the prize as golds, and it rly aint worth the time, now as i kow maze is gonna change so they wont be able to choose by maze owners name anymore, just the difficuly and maybe amount of items/gold im not sure.
Anyhow i started farmin em gobos, its awesome, vengeful or cheeky goblin is for 3.5k Koe marks, so every 4th day is a new goblin to my maze yey!
I also do goboball and signs of victory for goblins only nowdays, (yes i dont have any gold anymore=) but i hope this pays back when ppl actually goes into my maze (0 visitors in last 6months QQ)
