So I "get" prestige and why you do it. Cool. I just haven't quite noodled out when to do it. I've read some folks say you hit a wall. Some folks have said, "when things start to slow down". Is there some sort of like...common wisdom with respect to when you should Prestige? I just started playing on Saturday and haven't done it yet because I don't want to miss out on something that I get for pushing it longer if that's a thing. What's the rule of thumb for when to hit that reset button?

For reference all my little dudes are just L10 and I'm at stage 190 on my first play and have not yet Prestiged (even though I got the tutorial page about it like over 100 stages ago when I unlocked a 6th hero).

Thanks for any advice and apologies if this has been asked and answered.
