Diana is in a very bad spot in the current meta
Diana isn't so bad mages mid lane but seeing a mage mid lane is a rarity lately. While I always loved a good zed or talon match up its not even fair anymore.
I feel irelovant when playing Diana because the enemy builds a hexdrinker and an edge of night with merc treads. Meanwhile I have a hourglass and a rod of ages and I can't even last in lane without having to back constantly or dieing from losing trades due to how easy it is to buy ad items with Mr but no good ap items with armor.
