Regardless of balance, strong actives won't fix Support. They'll make it worse.
Yeah, I know. I'm PROBABLY gonna get downvote peppered and ignored, but honestly, support is becoming more about your build than your champ. In every other role, how you play is decided largely by your champ, and your build reflects the approach you're taking with that champ. In the support role specifically, when you're building support items, how you play is decided largely by your build. There's less emphasis on the fun of playing your champ and more emphasis on your Locket/Redemption combo, whereas last season it was Locket/Crucible. Support is being shoved into this really defensive, reactive, campy style of play where you don't really go out and interact with your opponents like everyone else does. You're just waiting around with your Locket and Redemption, playing that same 1 note.
I'm not saying that support champs or champs played in the role need to be as strong as carries on a lower budget. I'm saying that we need more items that emphasize the champions themselves and less generally busted actives like Locket and Redemption. More of this simply encourages making more insanely potent actives rather than actually tackling the quality of the game play in the role itself.
or something along these lines with the sole intent of shitting on specific midlaners using fast ganking.
could actually stack with this but doesn't give damage and is more costly to build in some cases depending on what sort of match it is. But if you build that then most likely you will want to get another damage item like leona's old favorite 
:3
just for their active uses.
or
for the active or passive
does the immortality thing
does the burst combo thing, doesnt need either item to be honest
this one can go
just because it scales with her passive and kit style though you'd probably only be able to afford it if you're ahead which goes back to the supports have no fallback fun thing.
) with slightly different orders (this is Lux's order).
will be joining soon if its passive is not majorly buffed. so little ap, so little healing. athenes heals less than redemption, gives you almost 0 increased damage thanks to the poor scalings on supports, as opposed to redemption which deals 10% true damage. its just garbage by comparison. i think the only person that will still build this next patch is MAYBE sona?
. and i KINDA SORTA wanna skip the gold generating item so i can build redemption earlier
, and since that +20% shield is worth 120 ap of scaling on them...
to just name SOME. (this item even used to be a late buy for all of them at some point)

and watching him 1v5 with the charged buff
