I tried Azir with Scepter in ARAM

Granted this is ARM, so it isn't a grounds for appropriate balance discussions. But holy shit it makes it much easier for his soldiers to get consecutive hits out.

I don't play Azir much at all and when I do I always end up shooting my soldiers too far out for them to auto attack or my opponent doesn't stay long enough to get AAed twice. But scepter just makes it so much easier to deal that damage. Combine his sustained damage with the burst of thunderlords and anyone squishy just straight up dies.

Sorry to be kicking a dead horse, but I think scepter (and maybe Azir but Riot's already acknowledged that he needs work) needs a cooldown or something. On a sustained damage AP champion it will never let up. On a burst champion you'll at least get some window of escape, but the window is nearly always closed if a DPS AP champion catches you in their combo.

Worse still is that any changes to lessen how much you can apply scepter (and I guess frozen mallet) would pretty much gut the champions that rely on it.

Mordekaiser and Gnar are the first to come to mind (there's Yasuo but to be honest I don't think anyone likes fighting Yasuo with Frozen Mallet).

Though this makes me wonder: If a champion hinges on constantly slowing the enemy to actually fight effectively, can they be considered healthy since they need to have a constant advantage to fight?

Take Gnar with Frozen Mallet. With it he can basically kite for days (and he can with BC yet it's not as painful to fight) and his opponent won't be able to escape without burning flash or a mobility spell. I'm not sure Gnar even needs items to help him kite.

Imagine if there was an on hit item that kept applying the grounded effect. Wouldn't that be absolute cancer to any mobile champion since it cuts out a huge part of their kit and with it their fighting power?

I have nothing against items that can slow, but I have to wonder if balancing someone around needing an item to do their job effectively is considered healthy at all (though I guess balancing them to work without items would make them super oppressive with those items).

At this point I'm just rambling. I probably don't really know enough on this topic to have too much of an opinion honestly.

So TLDR: Is requiring constant slows to do your job unhealthy and if so, how would we fix that?
