My 2 cents on the Janna "fiasco"
Okay, so, we all saw the Janna nerfs that made it to live. For people who don't know:
MOVEMENT SPEED 320 ⇒ 315 -W - Zephyr BASE DAMAGE 60/105/150/195/240 ⇒ 55/100/145/190/235
What I don't understand, though, is why Janna gets treated differently from other champions. She's NEVER been under 50% WR in the past 4 years, as you can see here. Other supports/enchanters have had a below-50% WR for some patches, but Janna LITERALLY hasn't been since early S4.
A common excuse is "but she's braindead easy to play!", but as I said, it's just an excuse. Let's take a look at Sona for example. Currently she has a 4% WR in Plat+ (1/5 of Janna's) and a 51% WR (-2,3% compared to Janna). But we all know what Riot did to Sona. Basically she was nerfed... 4 times in a row? just because new runes synergized too well with her and was left weak because she was considered too strong/frustrating to play against. Well, Sona isn't that hard to play (I'd say she's not harder than Janna) but she was nerfed to the point where she had a consistent 48%WR and a laughable playrate.
So... Why can't you do the same with Janna? Stats speak for themselves: Janna is not a "op hehe" champion, she's definitely broken and the fact that she's been receiving nerfs non-stop for 6 years is a clear sign of that. At this point it doesn't matter how many nerfs you throw at her (even though they're usually ridiculous love taps), she'll still be the #1 enchanter both in winrate and playrate because she's just too good at doing everything an enchanter should do. Even when she's "out of meta" (I doubt it really happened during the last 3 seasons but still) she still manages to mantain insane stats.
Other champions in other roles are instagutted the moment they reach a 52%+ WR, despite having low playrates, and left in the dust for months, or even years (looking at you, Viktor). But Janna? Apparently she's not a priority pick in pro play so it's okay to leave her disgustingly overpowered for SoloQ. People who say "spam Janna to D5" are right. It takes little to no effort to do good with her and being able to protect her carry requires nothing but a 3-buttons spells chain that does everything with low skill involvement.
Can you just admit that Janna is broken by design and that nerfs won't fix her core issues? Just put her in the tier 1 list for VGUs and do something serious about her, nerfing her damage or movement speed by 5 won't solve the issue and never did in the past seasons.
Not a rant, just wanted to point out how Janna avoids gutting whereas other champions get gutted for a patch or two in which they're good.
Tl;dr: Janna never dropped below 50% WR for 4+ years and all she's been receiving are love taps that don't fix her core issues. She needs some major work because she's the best pick in every situation, regardless of how many nerfs she gets.
