not so much. I'm regularly ranking within the top50 solo leaderboards of a season.
Top10-20 early season.
I mainly play solo, sometimes with a few friends (lacking lots of paragon thats why I always fall off the ranking later in a season)
I always try to improve the meta builds (which to be quite honest is possible) and play it the way I like. However this is not to be mistaken with playing for fun everything that comes to your mind obviously. You have to stick to OP items. sets and skills.
So I don't see the problem of the question.
There is already a community made up solo self found leaderboard as far as I remember. I didnt bother with that since you need to take screenshots of your achievements and GR pushs and such for them to be valid. I'm just lazy I guess...
The founder of this SSF leaderboard I think was Leviathan. He has some youtube videos about it and is one of the "Westmarch Workshop" guys. Correct me if I'm wrong, not 100% certain xD
