Sion Passives, Counter productive

Okay so Sions passives are counter productive. Having him lose % max HP every second makes it his passive counter productive by stacking HP or even just CSing, since he gains Max HP per kill. Here is why.

Once Sion dies he comes back to life, gains 100% LS and alot of AS, okay thats cool. BUT he loses a % of his Max HP every second increasing exponentially. So say for example you died, so you do 100 damage with every attack, and you have 1000 HP. SO with every attack you gain 10% of your Max HP. If you have 2000 HP you gain 5% with every attack, and with 4000 HP 2.5% with every attack. so by stacking health it reduces the total % of HP restored, likewise with increased damage comes increased % restored.

Now since you lose a % of max HP per second this means that as you gain HP or as you build HP items and your AD stays the same you have less time in your passive. Making it counter productive to stack HP, cause with less HP you gain a higher % of HP back per attack, allowing you to stay alive longer.

How do you fix this?

Well don't build HP. Well Okay, I have a passive that gives me infinite HP so im going to gain it any way, and If I don't build HP then once i do die and come back ill be so squishy that any one will be able to kill me again, since I have no form of CC once my passive goes off. So not building HP is not an option, sion is a bruiser and must have it or he will be worthless.

Well build lots of AD. Well okay, but again if I'm building AD then I'm not getting much HP. yea Ill get a massive amount of % HP back, but ill be so squishy that any CC will make me die in an instant.

Find a happy medium? Yea this could work. But I still have infinite scaling HP so as the game goes on I'm gaining less and less % max HP with each hit. Its just counter productive.

Well then why don't we make it a flat rate instead of % max? That would WORK! If we make him lose a flat rate of HP every second it would make stacking HP VERY productive for his passive, allowing him to stay alive longer. and it would not hurt building AD as well cause you still gain alot more HP back with all your LS.

For example if you lose 100 HP every second (increasing with every tick of course, so like 100, 150, 200, 250 ex....) then having a Higher amount of HP would allow you to stay alive longer, and having a higher amount of AD would also work productively since you can gain back alot of the flat amount with every attack.
