Getting to Mercury in Y1 was harder than beating Skolas.
HM KF isn't even that difficult.
It was on farm status in less than a week.
I won't argue that Trials is hard, I personally could never have gotten to the lighthouse unless I was carried.
But Skolas was hard. Most people wouldn't even attempt it unless everyone could cheese it with all Gallys during the week when there was solar burn. Otherwise no one would touch Skolas.
And from jumping from raid group to raid group, most people despite being well leveled still have a hard time with the hm kf.
Seems that everyone gets stuck at war priest, daughters and Oryx. Shit, most won't even do Oryx. I personally only do hm Oryx on my warlock because I want the helmet. Other than that I don't bother. The shit drops make the time spent taking him down not worth it.
Even now I hesitate to join hm raids even if I do want to do them. It's a crapshoot whether I'll finish it in less than two hours or get stuck at daughters after 4 hours because we earlier got stuck on the war priest. The difficulty is all over the place for different people and technically I could ask/require stricter rules to join, but I'm not a fan of doing that. I hate the whole "must have ToM, be light level whatever and know the strategy."
Anywho, hm kf is not on farm status. It's just not.
