The Netherdrake rep had a ‘good’ system for getting the rep.
It was time gated behind dailies but it also had another system of delivering dragon eggs which you would have to search for if you wanted that extra rep out of the time window.
Nowadays that extra rep system could (and should) be found somewhere. However, it’s nowhere to be found. (I also expect that if something like that comes back that it doesn’t get too obnoxious as searching for these rare dragon eggs xd)
