that's not endgame that's still part of leveling iirc
they are okayish to do before you can farm SR but totem hunting is nowadays better, don't know when you last played but there are monster totems now all over the world which drop legendaries
never did it, also not necessary for progression
yup, I think that's the ultimate challenge for a build, some of the quests are annoying as hell though.
high levels of shattered realm (75 or 80 iirc)
yeah that's GD's greater rift equivalent
so this is how GD's engame might look after reaching level 100:
- farm totems to get the legendaries you need to get a build going to be able to start doing SR
- climb SR and keep upgrading your gear
- once you have your full gear, kill the celestial bosses
after that? well all you can do is try to reach higher levels in SR and farm for better gear rolls, again doing SR... very LACKING. And you can reach this point (beaten celestials) with a fresh/ssf character in a couple weeks.
compare that to Diablo 3 where in addition to just getting the set and farming for rolls you also have LEVELED GEMS, ANCIENTS... and PARAGON LEVELS!
The POWER CURVE is much, much longer in D3, you can grind and power up your character for 100s, if not 1000s, of hours. Here, Greater Rift progression makes actually sense, because you progress further the higher stats you have. In GD you are limited to farming perfect rolls for your BiS gear past level 100, and that's it. There are no other mechanics to power up your character beyond that.
If GD had something like a paragon level it might do better, but then again SR is really kind of boring and predictable to farm.
