is Thresh really a tank support?
More a philosophical debate about what a tank support is. Thresh does well building defensive stats, but mostly because he lack any major scaling. The other thing I noticed is that Thresh really does not have any defensive abilities. He does have CC but so do many poke and utility supports as well.
Part of it is Thresh's goal. He's good at pick and catchout potential because he has his hook, and can position his allies with his lantern. Similar mechanics are shared with Blitz.
I guess What I think of Tanks supports are ones who have good defensive abilities, (and engage tools) while being less reliant on items for defenses. Leona's Eclipse gives her passive defenses, Alistar ult give him strait damage reduction. both of which have more AoE tools to disrupt the enemy.
Not debating whether thresh is good, (or good in the current meta) But is it a good pick when asked to pick a tank support? (maybe because your team does not have a tank)
. If it works, it works well, but if it doesn't (AKA he can't land his hooks), he doesn't have much to fall back on, and he suffers HARD for it.
) to make up for it, and practice diligence on soul collecting.
). Combined with his passive, he gains great incentive to tank up and fulfill more roles than most other champions would dare to dream. He is one of the very few jack-of-all-trade champions as a result.
