Sterak's Gage needs to be... changed

So as we all know, Steraks is largely being abused by a wide variety of champions that it should not be, and is very strong. most of these can STILL POP THE SHIELD.

Grants STERAK'S FURY upon taking 400 - 1800 (based on level) damage within 5 seconds (45 second cooldown). UNIQUE – STERAK'S FURY: Grants increased size, +25% additional base attack damage, and a rapidly decaying shield based of 30% maximum health for 8 seconds.

now your thinking... 1800 damage at level 18? they wont have any health to pop that! well, let me tell you that based on my understanding, the cost to activate the shield buff increases by 77.8(rounded) HP per LVL. Wanna see a complete list of people who don't gain at least that much per lvl?

Here:

1. Anivia +70
2. Annie +76
3. Brand +76
4. Cassiopeia +75
5. Hiemerdonger +75
6. Karthus +75
7. Leblanc +76
8. Lulu +74
9. Mordekaiser +73
10. Nami +74
11. Shen +73 (Why?)
12. Sion +73 (Can stack health)
13. Sona +77
14. Vel'koz +76
15. Zilean +71
16. Zyra +74

Gnar is not on this list, but his mini-form would be+65 However, mega is +108.

Notice its widely Mages, and support mages. and shen. why is shen so low.

NOT A SINGLE ADC FALLS BELOW THE THRESHHOLD(fun fact, the lowest lvl 1 hp is Anivia with 467.6)

HENCCCCEEE every single adc and person who can abuse it can use the shield if at full health.

this is why its abused.

My suggestion:

Make it so theres a HP base restriction, like warmogs, have at least 3000 health to activate the passive, this should help.

either that or nerf Max hp for the offenders... looking at you graves and quinn.

Edit: I noticed that unless you have 0 health, the +400 from steraks will provide the base 400.

also thanks for explaining the she situation to me! makes sense.
