support power needs to be separated from marksmen power

and vice versa they're too intertwined with each other right now

i'm gonna start with support power-budget and items since I have more experience on them, as someone who has played support as either a main or a secondary since I started in season 4. I've always held the opinion that support itemization has been far too broadly valuable to be healthy (Locket, Redemption, etc) but we're seeing the opposite now where their items are being tailored specifically to one person -- the marksman. The last three different iterations of Zeke's have all been about enhancing your ADC, either by giving them crit, or by giving them bonus rightclick damage (which means ADCs get the most of it), and perhaps the biggest offender , which, if you CAN build this item and you AREN'T, you're probably going to be insulted. There aren't any items that offer significant offensive boosts for other teammates who might be more apt to carry, and the defensive items are generally going to be used to protect the ADC above anyone else (which is fair enough since they're important, but for usually being AOE actives it's a bit disappointing.) A lot of enchanters in particular have gameplay that's sort of devolved into 'keep shielding this one guy and we'll win,' and I think that's really unfortunate.

To me, the biggest problem with support is that Riot is very tunneled on a specific 'play-style' they should embody, instead of giving them a broad selection of items for a class that IMO should have the highest build diversity by a wide margin; items with debuffs, buffs (that aren't explicitly best on an ADC), enabling champions to do certain things, and so on. In addition to that I think the CURRENT playstyle of being very protection-heavy could be done in much more fun/interesting ways than just hurling giant shields on their teammate and forcing a stat-check; something both parties actually have to play around would naturally set them apart from gluing to ADCs while still keeping them competent at doing their job.

I think ADCs stand to gain from this change, too; as of right now they are going to be nerfed again and again to compensate for the new power supports have come into, until they're no longer so out of whack. I'm not as experienced for this group of champions so I think I'd be overstepping if I said too much, but my biggest hope for separating them from being tied to their support and the support being tied to them would open up a LOT of leeway to diversify the ADC roster better, and might let us finally solve the age-old problem of these champions constantly having 3 or 4 picks who dominate the rest.
