well, about my plans? i will try for once to join the meta in groups to pump my paragon, only 1300 NS atm. so i'm thinking about going monk, and HOPEFULLY they will be in the speedfarm meta(although i think speed runs will remain the same, 563276 necros and a barb). otherwise i'm fucked yet again.
if you do plan on playing solo, DH is probably the best option out there, they are beasts for soloing journeys, especially now with the MS buff you will probably complete the journey half asleep. DH has always been my first option in seasons because of how easy they are to solo it, only problem was t13 rift in 4 minutes and maybe 1 conquest. now with MS buff there is no question, only help you might need is if you are going for boss mode conquest, everything else is easy solo.
its unnatural to balance all builds 100%, because you would see set bonus grating 1263.57% damage. on a serious note, its impossible because of all the different variants in a build, density, stat interaction, toughness, skills make it a really difficult task. even gear plays a huge role.
a 500 para MOTE barb can destroy a gr70 with less than optimal gear, where a ww barb with same level struggles in GR60. but as gear/para gets better, ww is top barb build.
and the problem with the diablo community in groups is that they will ALWAYS go with the absolute best meta. even if a class is 98% compared to another class they will never run with that, because hey, its not the best.
