So does anyone know why exactly mana regen runes are so much more popular than just mana runes?

I just calculated how much time it takes for regen runes to give you just as much mana as the plain mana runes. Mana runes give you 11.25 mana per glyph, while flat mana regen seals give you 0.41 mana regen per 5. With those numbers I calculated it takes almost 2,5 minutes (137 seconds) before regen runes regenerated just as much mana as the mana runes give you straight out of base.

Now you might say "yeah, but regen runes start working as soon as you cast a spell", but the same can be said for mana runes. With mana runes it'll take you longer to run out of mana (because you got more of it), which means your base regen will also have more time to regenerate mana and instead of having to wait 2 minutes to cast another spell you already have that mana (though after spending it it will take longer to regen).

Another point is, how much time is between your recalls/deaths in general? I think on average you recall/die 5-10 times in a 30 minute game, meaning that you recall roughly every 6-3 minutes. Meaning that mana runes would be very close to being just as efficient as mana regen runes (giving you just as much mana as regen runes would between recalls/deaths half the time or more). Add the fact that blue buff becomes more effective the more mana you have and you have runes that are pretty underrated.

I'm not saying they will be the best choice in every situation, but they definitely aren't as inferior to mana regen runes as some people might want you to believe.
