What I have started doing is to skip the " defend the perimeter" event of the plinx chain. Its a long event with a set duration (roughly 5-7 mins) with little to no drops. I have managed to extend when my DR kicks in to 4 hours(at best) instead of the normal 30-35 minutes.
Make sure your groups knows what your doing or they could replace you
*note* By skip i mean completely log out of the game for 5 minutes, if you swap to an alt your boosters will still drain time.
Not true, though haven't tested this for 5 days but I doubt the maintenance patch on Monday/ Tuesday has changed anything. But when I was karma farming (and did so for 7 days straight), boosters were not effected if playing an alt. This is really important as using alts to avoid DR mean your alts were probably using boosters too. Never did my booster time go down when playing an alt.
I need to time that part of the plinx chain but to me part 3 was more like 4 minutes and you can speed it up, you simply knock the enemies out of the circle. Also on desolation, the zerg fest hits the mobs so hard they rarely even get into the circle making this event finish even quicker.
DR rates have also been altered in the last 7 days. Prior to this you'd need 3 characters to avoid DR if you were hardcore farming with boosters, now you only need 2. Farming without booster you can for 45-60 minutes now before having to change.
