I also attempted this at Level 4 Solo with a "Fresh off the boat" artificer, it took roughly 3 minutes to "get the idea" of whats going on in the quest, and afterwards it was a simple matter of "Backspacing" around to find the crests and bee lining to them.
I like the idea of the quest however I see some "issues"
A) It GREATLY favors "Haste" and movement speed increases, which at level 4 aren't exactly available in abundance
B) Jump is REQUIRED to succeed as there are some crests that are impossible to get if you dont have jump.
C) Having ROGUE skills is also required to succeed.
So far it seems the best strategy from my 1 attempt
would be to split up and zerg with at least 1 Rogue Skill user hitting all the trapped and locked areas, which is "Probably" the intent of the quest hence is name "Dr. Rush More" which IMO is a great play on words for the quest.
This is going to be a MAJOR "Self Sufficient" ZERG quest, and with the limited number of attempts allowed per day I cant see people being willing to "Suffer" having clueless noobs running it with them who might cause a failure.
My advice is to, at least at lower levels, increase the bonus time added for opening doors since the lack of haste and other movement speed enhancers might be an issue. However I'll need further testing in a group before I can make any solid recommendations.
