Mage pot when split pushing?

I was just thinking. Okay, so mage pot does 25 damage to turrets every hit.

So in theory, let's say you're playing . You're split pushing all day right? And you think to yourself "Man, I gotta shred these towers down faster." So I did some math, with 25 true damage on hit, for split pushing purposes Sorcery Pot is better than all the others. Because obviously 25 AD from AD pot won't be exactly 25 damage, and the 15% from elixir of Ruin would only be better if you did about 170 damage to towers.

So splitpushers who aren't full damage such as would actually push faster with the Sorcery Pot than with elixir of Ruin, which gives 15% damage to towers.

So in conclusion I've decided would be better on champions like the above for splitpushing. (Hell, it's probably fine either way on Jax). But the pot would give Shen some actual damage for splitpushing when waiting to ult in to his team, and Shyvana would proc the true damage twice on Twin Bite (with BotRK and Devourer you would shred through towers almost as fast as ).

**TL;DR: ** True damage on towers from Sorcery Pot can be used for split pushing if you have less than 170 damage on an auto attack (then go elixir of Ruin for max damage to towers)
