No, her poke is unreliable, her Q is like Morgana Q, but no utility.
She has no cc, no high enough damage to burst target (given enemy sup and adc are together), no tankiness to leave once in melee
Her only utility is heal, which is only good for low HP; and buff
We can take other non-meta/weird picks, that are still viable and played.
She has cc
She can heal ally decently, but only once itemized and maxed, and buff
She can apply invulnerability on ally
So she can fulfill basic utlity support duties: has heal, has cc, has saves, has debuffs
He has 3 cc, one of which is hard cc
He can poke and all-in, having tankiness to leave once in melee
He can soak damage
He can buff and debuff
So he can fulfill basic all-in tanky support duties: has good cc, has tankiness to go in and soak damage.
