There is nothing wrong about supports going in solo lane
Why people are afraid of buffing supports's kit because they would be able to solo lane?
Lulu was broken in solo lane because she was both a support AND A LANE BULLY MAGE they nerfed her waveclear, and her poke through minions. It isn't the case anymore Tahm Kench was broken in solo lane because he was both a support AND A JUGGERNAUT, they nerfed his damage it isn't the case anymore
picking a support in sololane means you sacrifice lane power as well as consistent damage in exchange of utility for later in teamfight
it was always a strategy, even now i see
going mid and building ardent+athene, most common pick is
, you pick him mid, do not kill anyone and just try to survive for later to bring stun+ult+slow/ms boost
stop being afraid of trivial things, dota has sololane supports since years it's only a strat
