What are your guys thought on Ekko's current state?

I honestly (in my own opinion) think that Ekko is broken. Not extremely over powered, but broken. He doesn't really have any weaknesses, and he's not fun to lane against due to his small amount of weakness. So I wonder if you guys think if he should get a nerf on something, or just be left as is. What makes this more scary is that the new jungle item RuneGlaive is coming out here are its stats...

RuneGlaive Enchantment:

40 AP 200 Mana +10% Cooldown Reduction UNIQUE Passive - Spellblade: After using an ability, the next basic attack is converted into magic damage and deals 75% Base Attack Damage (+30% of Ability Power) bonus magic damage on hit in an AoE around the target (1.5 second cooldown). When attacking a monster, this also restores 6% of your missing Mana."

Not to mention they're reworking a lot of AP items, and from the looks of it Ekko's going to actually be over powered and broken if these changes do come in.

I think he needs a nerf soon. Just on some of his AP Ratios. Also, on the note of a bug fix... If Ekko gains health when he ults, because he's going back in time after taking damage right? Well how come he doesn't lose health after gaining health, and going back in time. I hear all these people saying it doesn't have a mana cost because Ekko travels back in time, but that makes no sense if he doesn't lose health after he gains health when going back in time.

Anyways what are your guys thoughts? I just think a tiny nerf on his AP Ratios, and maybe some lower base DMG nerfs would be fine. Nothing that makes him unviable, and something that still makes him take a lot of skill to be really good with.
