A thing to keep in mind about all this kinda stuff;

The game is what you make it.

It's not a competitive endeavor. Try as some might, you have to opt into any competition, so it's not competitive.

If you want to chain-strands all day, go nuts.

If you want to run other maps, go nuts.

Personally, I just never run the same map twice in a row, am not preferable to any. I like Strand as much as I like Cells. Diversity in mapping is the most important thing to me.

The only factor I take in, is which boss is for the map, so I don't roll mods that make it insane and rip.

They could make Cells hand out exalts, and people still wouldn't run it, because they just don't like it. That's totally fine.

The only fear I think that is actually notable, is that players chaining strands because they can't escape their own thoughts of inferiority otherwise, will burn-out, and that's something GGG is probably keen to avoid. I know for a fact if I cared about 'efficiency' and tried to run Strand all day, I would probably burn-out and play a hell of a lot less.
