I've been seeing the hours spent in this and don't even think this is worth the time to really do, honestly. E1S-E4S was definitely more the speed I'd expect for something that is "challenging but still doable". If a good group can punch through it in about two to three weeks than it's definitely worth the time, but otherwise getting stuck on something like E6S or even E7S for weeks on end? People are spending like 3 hours a day on this stuff in some cases. That sounds like chinese water torture and I've only been stuck on E6S for maybe 3 weeks because of pugs and just general bad luck.

It's one of those things where if everything goes and lines up it's great, and for most it's probably not going to line up.
