"Double pick rate"
Her pick rate at all ranks the past 7 days is 2.31%. Her pickrate the patch before the midscope was 1.66%. That's .65% more, a bit over a third, not double. And before you say Bel'Veth had a lower pickrate than that before that patch, no she didn't. Three patches before the midscope were all above 1.6%. Bel'Veth's pick rate hit a low for about a month, then it started going back up before the midscope. Bel'Veth's pick rate IS double, if you deliberately go out of your way to only take into account the worst patch popularity she ever had.
Her pickrate is continuing to go down, hitting a new lowest for a certain rank every few days.
"Bel'Veth's depth went from a fair bit underaverage-"
No. No it wasn't. Bel'Veth was one of the most deep champions in the game. I've watched the stats on that since before August even said he was working on a midscope. Bel'Veth's depth before the midscope was around 1.17. To put that into perspective, that's higher than Yasuo, Riven, Singed, and the vast majority of champions. Bel'Veth's depth now is 1.31, .14 higher. So sure, her depth wasn't underaverage, but it is still higher right? And yeah, it is, but Bel'Veth's depth shortly before now was 1.46. Her depth went down by .15 in the past couple weeks, and just as her pick rate has continued to bleed, so will her depth.
Bel'Veth's breadth increased by .15. From .39 to .54. A significant increase yes, but again, it is still dropping, bleeding every day.
And before you say Riot's API is somehow wrong or not as accurate as Riot's sources themselves, need I remind you of all the many times Rioters have changed their opinions after looking at that API? Need I remind you of the fact that the API'S statistics on champion depth have always lined up with what Rioters have said they were before? Unless it was just coincidence that what Rioters said the depth was and what the API said the depth was lined up every other time except when it disagrees with August.
"E should prioritize champions"
No, it shouldn't. People love to think about all the times the E hits a mon-champion when they mean to hit a champion, but ignore all the times it hits a non-champion when they mean to hit a non-champion. Ignoring the fact that having the E hit the right target is a key part of Bel'Veth's gameplay, and a highly skillful mechanic that Bel'Veth has more than enough tools to play around, it isn't some flawed mechanic that you can't play around like a glitch or something, it is a very purposeful part of her design. Beyond that though, do you want Bel'Veth to be weaker agaisnt invades? Because that's what E prioritizing champions would do. Want to use E to finish off a camp while an enemy champion is going in on you? To get the heal, not only from the E lifesteal but from killing the camp? Nope. Your E will waste all hits attacks dealling sub 50 damage total on the enemy champion, and you'll just be sitting there letting the enemy do whatever they want. Want to use your E to clear a wave? Or use it to heal with the lifesteal on low health minions dealing high damage? Nope. Again, you will waste all your attacks on a champion. Because versatility? Dynamic gameplay? Counterplay? Skill expression? Who needs it! All you people want to do is mindlessly press E and continue to let your brain cells leak from your skull. Bash your head into the keyboard and right click. First the midscope makes the E damage near meaningless and makes just right clicking almost always better, now you'll have literally no reason to do anything other than press E on cooldown. Can't use it for literally anything other than the DR and stacking R passive. Why even have it do damage anyway?
'People will always choose security over freedom'
You people will always choose easy power over dynamic versatility.
"W should reset Q"
Yeah, because why did we do the midscope anyway? Screw it, just band aid fix the band aid fix! Instead of smart and simple changes, let's massively overnerf, then make unintuitive and lazy "fixes" that will cause more problems, after all that's what the rest of the midscope did, why shouldn't changes to the midscope keep up the pattern?
"Old players like invades"
Old players didn't like invades. Yes, some people really liked Bel'Veth specifically because of them, but the majority of Bel players were more than happy to give up level 1-3 invades for better scaling. What no one was happy to give up was E damage, lifesteal scaling, laning ability, remora plays before baron, meaningful W E and W R combos, meaningful build diversity, meaningful tactical diversity, high skill cap, even the attack after cast. August doesn't understand what people liked about Bel'Veth before the midscope, and he doesn't understand the issues people have with the midscope. Can't wait for him to only double down on the bad changes while walking back only the good changes of the midscope! You'll all say you love it I'm sure, and then Bel'Veth's pick rate and depth will continue to bleed
