Make Thresh finally synergise with tank support items propertly(especially relic shield)

I'm waiting for this a long time. I know Thresh is ranged, but he's also a tank support. So i came up with some ideas that may work. Plz leave a comment telling me what do u think about this changes:

Passive(s):

•"Damnation": unchanged

•NEW: "Madman's Sickle": The current passive effect on his e(Thresh auto-attacks deal bonus on-hit magic dmg equal to the number of souls harvested by Damnation, his total ad and an extra base damage based on how much time he has spend since his last attack), but with a few changes:

•Less base damage early on. •The base damage will still scale with the ranks that u put on your E-Flay. •A NEW EFFECT: When Thresh waits long enough for the maximum bonus magic on-hit damage(the indecator becomes red), he will have two options:

• Either waste the bonus on-hit magic damage on enemies • Or execute enemy lane minions if they fall below from health threshold: 200-280 hp based on level( he will know when to execute them because an indecator will warn him) by walking at 125 range near them(an indecator will let him know about this 125 range), owning him always a soul(maybe not that), while healing the nearby lowest hp ally (similar to relic shield) for 7.5 health. This effect will have a cooldown and as u can imagine it synerges with relic shield, because when an enemy minion dies, its passive procs.

Because relic shield will be too strong on him(it terms of the heal), make the heal of relic shield be half of its current value(7.5 heal) for ranged champions(this will balance this new recommended passive on Thresh and will also nerf the current annoying meta where adcs buy relic shield as a starting item, because of its stats, gold and heal passive).

•NEW: "Madman's Armor": Thresh will increase the effectiveness of support items that are stronger on melee champions, but they can be owned both by ranged and melee champions(knight's vow, zeke's convergence) by as much as 25% based on the number of souls harvested(i don't know how much).

Disclaimer:

Leave your thoughts for these two new passives that i thought and don't judge their names as well as the parenthesis of the text please. U may think that the last passive is a little bit too much, but think that: Thresh is supposed to be a tanky/beefy support champion(he dives in with his hook remember?), so having less tank capabilities from certain items because he's ranged makes absolutely no sense to me.
