I have severe problems with this quest, Zojja and mr Sparkles just stands there most of the tries I did and only ever assisted when I am almost dead and the Sylvari just kamikaze himself in less than 10 seconds. I have managed to get the first golem down and got Plunka on the run but alone against the next three golems and Plunka I stand no chance.
Also I can’t get help from my guildies as they never get the option to enter the instance when I enter, I have assisted others in their quests just fine but here it fails and they can’t join me.
