Ori is unique in that she doesn't scale with levels as much as other mid laners. I'm not saying she doesn't spike with levels. She does, but it's hard as fuck to take advantage of her level 6 spike since all 4 of her skills are kind of like skillshots.
Let's look at zed, ahri and annie. At level 6, they'll all in with little to no effort. Orianna needs to position herself and the ball well to pull it off.
So let's ask the question; why take the risk?
You can just farm for a deathcap and become a monster in team fights instead of making a mistake at level 6 and potentially get shoved out of lane or die.
I don't know about you but Ori's main strength to me is her E in team fights. She can single handedly win a fight by making her front line or herself unkillable by kiting and shielding.
Plus, Ori can take advantage of the mistakes of enemies more so than any other mid laner. It's not difficult to place your ball and watch an enemy carry blindly walk into it since they're too caught up in trying to clear waves or poke in a siege. That's why I said she's not difficult to master in solo queue. Solo queue players make tonnes of mistakes. No other champ in the game can take advantage and deal out such hefty punishment for enemy mistakes that easily.
Additional thought: If you play ori with the mind set of solo carrying with damage, that's a risk. It's like building full ad on rengar.
The ori players I fear aren't the ones doing damage but the ones who make their team untouchable and capitalise on my team's mistakes/missteps.
tl;dr Due to her insane scaling with items and the ball, Orianna can take advantage of enemy mistakes and instantly win a game out of nowhere with very little effort or skill. I'd even argue it's one of the easiest and harshest ways to punish the enemy's mistakes in the entire game.
to me what you're saying makes no sense because all of that applies just as well to, say, leblanc. one wrong move by the enemy adc and she can one shot them without even doing something mechanically taxing
why does leblanc take skill to take advantage of adc literally walking into sigil of silence range and ori doesn't?
and similarly applies to lissandra or xerath or any other midlaner capable of easily oneshotting/severely chunking someone that overextends.
and actually ori has more trouble than usualy for that because you can actually dodge/flash her ult. you're deriving difficulty from a "skill" that most mid laners have and that ori isn't even particularly amazing at. yeah if you fight in a choke and land a good ult you can turn around teamfights, but that's a super reductive way of looking at her and you're for some reason glossing over any other case that isn't "enemy stupidly walks to their death", which imo is not representative of an average game whatsoever (i mean, it happens, but for both sides, and if you're assuming that the enemy team is dumb like that then you have to assume also that the friendlies are not gonna be lcs caliber at taking advantage of one good shockwave)
i think you're mixing up two completely different things
Also zky teach me Ori itemization
duno if you're asking serious but rex is pretty spot on with the whole mindset thing, you want to get lots of ap but she can safely build things like merc treads or zhonyas instead of deathcap because of how much "base" utility she has. you still want to try and get deathcap as second item every game but surviving is often more important than dealing lots of damage as ori so you can keep spamming shields and slows/speedups
also athenes is useless right now unless you really need the mr so u should always try going morellos as it gives better regen
i'm trying to think how lumen's echo fits her but i think it's gonna be a fifth or sixth item 90% of the times
so it's gonna be morellos deathcap/zhonyas sorc shoes void staff and the other two ap items, in whichever order you feel needed. i guess you can get liandrys as a sixth item or something defensive, but i don't like going defensive items on midlaners anymore and liandrys is weird. maybe rylais, who knows. sixth item doesn't really matter all that much.
the reason u don't get lumens is because if u don't need to survive against zed (zhonyas) u just get deathcap that benefits both your damage and your shield
also blue pot is really good on her but i don't really understand new blue pot all that well cos the true damage has that weird champions cooldown that i never understand if it's general or per-champion
Zztop voidlings give the owner CS? Never bought that thing
yea, they do!
i dunno who you'd build that on, doesn't feel like it's something that you can rush and like i guess it could replace resistances-only items like fh or thornmail or maybe warmogs since it's just health, but i dunno.
the active seems fun, i'd try the item a lot if i liked to top lane
