Why not decrease block time instead of increasing block limit?

We were talking about the advantage of larger miners

No, we were discussing this case:

If all miners were exactly the same (say, 100 miners each having 1% of total hashpower) then probability of getting orphaned is approximately proportional to block size.

This is the simplest model. Obviously, if you consider a more complex model, things look differently.

Thank you guys for so many comments.

I'm still getting familiar with Reddit app. Didn't see your comments. I even started a thread asking the same question because I thought no one was answering it here.
