I dont see 
going oom
And thats not even including 
Its not like theres any meaningful tradeoffs. The only difference is some champs require the skill of managing a resource or are forced into buying certain items while many (mostly AD) champs can buy damage or defense items immediately.
ForgiveColour4 votesMages gated by mana in 2017 LUL
fuffychan2 votesNot sure if stupid.
Go play a mage without buying a single mana item, like most of the above mentioned champs. Lets see how long you last.

BALDG1VEN BOOMER2 votesBoth of you need to stop slandering each other, everyone will have difference of opinions regardless if you find it morally correct or wrong.
DrCyanide1 votesI regularly avoid mana items on Xerath, but that's because I can mitigate the mana costs with his passive and get an earlier item spike than my opponents. It's a little tough up until level 9 or so, but after that I don't even have to try and manage it.
Jo0o1 votesYeah, but mana items are generally strong. It's not like they fail to appreciably add to the Mage's AP and such.
Jo0o4 votesAm I the only person who has occasional mana issues as Darius?
Rarely enough to stop my normal abilities, but it's reasonably common for me to get a fully stacked passive and then not have the 100 remaining mana necessary to dunk. Especially at low levels.
ModKnightsKemplar1 votesThis, but for all champs.
Yes. Supports and mages are the most prone to spam spells, and thus often easier to run oom. However, other champs are tuned around mana costs, as well. If you spam spells on Darius, you will run oom. If you spam spells on Nasus, you will run oom. If you spam spells on Miss Fortune or Varus, you will run oom.
The OP's premise is flawed. Mages and supports are NOT the only champs to run oom.
fuffychan1 votesThe only time Ive gone oom as him is after Ive got a quad kill with ult and ran out of mana for the 5th.
Jo0o2 votesDarius's follow-up ults are free if he's getting kills with them... that's not a possible scenario.
fuffychan1 votesReally? Then youre proving the point of my thread LOL
I havent played him in a long time anyway so they must have changed it
Jo0o1 votesSure, but he can't spam abilities in lane.
Skilled Darius players (Which my Silver ass does NOT fall under) aren't "gated" by mana in that they frequently run out, but rather are "gated" by the fact that they hold their abilities back in order to find times to make the most use of them. Darius can't simply spam his abilities in lane. Unlike many mages with the appropriate items, I might add.
NinjaGuy693 votesI dont see
This couldn't be further from the truth for any of those champions. Maybe (and that's a long shot maybe) Kha'zix isn't that bad but the rest are heavily gated by mana. Completely misinformed statement on your part.
And thats not even including
I will agree that some of these champions should probably be gated by mana, but that presents another balance scenario for the Live Gameplay Team.
Mages are gated by mana because they would win a war of attrition against a considerable amount champions by poking them to death if they never ran out of mana.
robotmaster2 votesVald? Anyone.
My Heartshaker2 votesAre you sure?
usually is all they need to never run out of mana.
fuffychan1 votesRiot set up that "mage rework" to force all mages to NEED that item. Theyve admitted that it was intended to be a "core item" similar to 
to "get them going". I dont know why they did that, because it reduces build diversity.
ForgiveColour1 votesTfw mages have more build diversity than any other role

Are you sure?
which u don't just on champs like or most mage supports.
also during landing phase.. the VAST majority mages CERTAINLY have issues with mana is great once teamfight start and kills and assist come in. but its nothing like the old 
giving you % mana each second based on what u were missing..
Big Lincoln2 voteson the other hand these champs can't also afford to sink gold into regen items and mana items that also provide AD don't exist besides 
, which isn't worth building except on ezreal and urgot
do you want them to just slap mana on some AD items and raise AD mana costs?
fuffychan1 votesI want them to actually have to think before they attack instead of simply spamming.
I mean look at a guy like
Why would you ever NOT spam every skill?
dangopee2 votes
are very mana gated just to name a couple. Especially Vi, even late game.
Yaśuo Main2 votesAre you questioning how you can't see champions with no mana resource bar never run out of mana?

Both have huge mana issue and have to buy a a mana item 
or 
basically
But yes most everyone else you listed have mana but there costs are so stupid low they might as well not have it.
Zelorxon1 votesAs a matter of fact, where i get proven right once again, but i don't even care since i know i'm right by default, the problem is not nerfing the play, but buffing the counterplay.
The answer to that was being able to go double doran, which solved the problem of pushing after lv7, but since riot WANTS to create toxicity since i bet my ass that you don't even know what happens at lv7 and why it's so crucial to push at that mark, they pretended to listen to the cries of their puppets (which i call them bronzetards, but it's not limited to bronze) and nerfed the double D.Ring, which will be eventually responded with ring+flask for the mana sustain but will lower the early ap, making mid lane an even more passive role, but since people don't know about rotations and powerspike they'll attempt to go and score kills in lane, which will lead to a 50%-50% situation of winning or losing, and thus people will get more frustrated since they'll push plays that are not supposed to happen and the game will be even more confusing and chaotic, since players are not responsible people that know when do something and when don't.
All because bronze V cried (AFTER IGNORING SOMEHTING I TOLD THEM AT THE BEGINNING OF THE SEASON, AND NOW THEY'RE COMPLAINING ABOUT IT INSTEAD OF RIDING THE WAVE) and pro play abused 3 rings, which they're already adapting so it won't matter at all.
