when is it time to stop caring about leveling?

Usually I just go for "get as high lvl as possible" but around 84-85 it starts going really slow unless I have 73+ maps, and on new leagues that can be tough. Highest I have gotten is lvl 93 and I was hoping to get it to 100 some day but im going to say it right now, it aint going to happen. Too much of a grind of me to handle.

When you get bored with your char. That's the time. Or when you realise that your build can't go into very late maps (time to reroll), coz you die as quick as you gain 10%.

85 is the goal, higher is a bonus

Up until about 85, you get stronger as the enemies get stronger. But once you start 78 maps, the enemies don't get any stronger. So, while it is more difficult and can feel tedious, any push you can make over 85 really pays off in spades in terms of feeling like you are actually more powerful, as it's the only time the enemies aren't growing with you. My two prime toons are 93, and I am trying to get them both to 95 now. It's hard though - you stop thinking about x% of XP per map, an instead view how your XP will budge by doing multiple maps (eg.. if I do these 6 maps, my XP will move 5%).
