Sona/Zyra are still trash tier since preseason 4
I think they still need alot of buffs, they have been trash since ages.
They are bad regardless of the metagame, don't sell me the thing that this meta "does not fit them", Sona/Zyra are bad and that's it, we went through 10 different metas (even opposite ones) from S4 start to now and they have been irrelevant in every single one of them.
We basically had every single meta we could possibly have, and they have been shit in every one, how are they not trash tier again? Because of soloQ winrates?
I think the itemization is insanely bad for them also: spellthief is bad, sightstone gives useless stats to them, mobi boots are decent but they are better on pick supports.
You could argue that Zyra is not a support, whatever but Sona definitely is.
P.S. i'd like to point out that Zyra definitely had periods in wich she had <50% winrate, so that argument doesn't even work, her winrate and Sona's are super volatile.

Try the homegirl.
but I've come to see that either I just don't have what it takes to make her work or it's just the match ups are always so one-sided.
