Press the Attack and Lethal Tempo are too similar

For now, we'll set aside the fact that they contribute nearly identical amounts of damage to champions who would ostensibly want oodles of attack speed (Kog, Kayle, Vayne, ect) since that's a similar but separate issue. Instead, let's focus on what the keystones actually DO.

They both offer increased sustained damage. They both offer an explosive burst of damage (giant IAS boost, three-hit damage proc). Press the Attack also has the added benefit of boosting skill damage (and allied damage) against the target as well. As a result, people are just going to be using whichever one happens to provide the best damage source and ignore the other. Sound like a familiar problem? It should.

Rather than JUST nerfing PtA and buffing LT (or whatever Riot decides to do) I think they both need some change in functionality to help resolve them better. Here's what I've been pondering:

Press the Attack should be JUST about steady ramp up and steady DPS. It should be the 'hurt more' rune of choice.

Lethal Tempo should be JUST about providing an explosive boost in basic attack power. It should be about dumping a whole bunch of damage in a short span of time before going on cooldown.

If Riot doubles down on those two identities, I suspect they'll have an easier time making both runes feel useful.
