but you don't level Leona's W for the damage, you level it for the armour and MR bonus increases. and it still doesn't do that much damage, really... like maybe it can clear a minion wave around midgame, i guess? it's seriously not strong at all, and does nowhere near the damage of those other skills you listed, except MAYBE if you have an Abyssal Scepter and they aren't building MR at all, or you're building AP Leona, which is a kinda meh idea anyways...

your examples of tanky supports you don't hate aren't much comfort, since Thresh is barely a tank (he's not even classified as one by riot anymore, iirc) and Taric is kinda not viable atm, since his kit is outdated...

that might just be me being picky tho'
