@Meddler Adding executioners calling (the way I think you are) is a bad idea

Grevious wounds is a fairly archaic mechanic that needs to go. If my assumption is correct, you're reinstating EC with some different stats and building into a larger item, both with a conditional grevious wounds effect on autoattacks of some kind. I know you guys have been phasing GW out of kits for some time (there are only 2 left iirc), and that's the right way to play it.

Now it is possible that EC will be fine due to whatever condition you put on the grevious wounds effect (or you dont add it at all and this thread is pointless), but it is much better for everyone involved to smooth sustain curves for all champions rather than force GW purchases.

For example, let's say you're playing Lux vs Vlad. You want to get Athene's for extended poke wars and the mana return in long teamfights, but Vlad is going to go crazy on your team, so you have to build Morello's. You don't really think about it at that point, you just know he can't sustain from low hp.

Now from Vlad's side, you want to make some plays with all ins against the enemy team, taking a lot of damage and sustaining through it at low health. But wait, you can't do that, because a member of the enemy team bought X grevious wounds item.

The counterplay stops the moment someone buys an item, with the only option for their opponent being "dont drain tank like you were designed to past half hp." Kind of like how Zed relegates himself to splitpushing and ulting tanks because the enemy carries have Hourglass and QSS. It feels better for everyone involved to simply even out sustain power all around, rather than making sustain overbearing without grevious wounds and garbage with it.
