Rod of Ages 5.13 changes

Why did I build Rod of Ages (RoA)? To give my AP champion some survivability instead of being super squishy and for those who don't need huge mana items. Pretty simple concept.

But in 5.13, the MANA of RoA got a buff I personally dislike... And lost some of it's tankiness. I'm now finding that the item is giving champions like Diana and Azir too much mana. It was fine before. I didn't build RoA for the damage. That's a nice but unnecessary buff.

TL;DR (Even though it's not that long) It just bothers me to see my champion with less health than before. And seeing I have too much mana. I'd rather have health than too much mana.
