You read my post and quoted my post and still think im not aware of LoN?
Of course i know what LoN is, my point was that i fail to understand the desire to farm up a dozen ancient legendaries, only to shoehorn them into a build that is already catered for by a set.
I get the desire to cobble something together to play an otherwise unused skill but far too often it seems thats not the case, either its using the same skillls as a set build for barely any improvement or only half ancient because the gear hasnt even been collected.
As for your set builds made obsolete, thats only emerged this season with the new gem added in, and even then its only Necro and WD that have noticable power gain.
Well if theres no better explanation for it i guess its just laze, copy the top spec on the leaderboards cos theres a lack of will to search for current builds or make their own.
