Luden's Nerf is going in the wrong direction

As we recently saw on the PBE, Luden's Echo got a pretty sizable nerf to it's stacking rate from spellcast (from 20 to 10), and a small ratio nerf.

This makes the item almost exlusively good on poke champs or hyper-god tier mobility champs, and the like, but kills it on Machine Gunner mages that tended to be immobile but cast spells really fast to get multiple Luden's procs in a single fight instead.

Instead of letting Luden's scale on spellcast exlusively for it's recharge from spells, can we please make it scale on spell HIT instead, or half and half? This means you actually have to land skills, and hit the enemies, to keep it charging, but if you just keep whiffing skills as a poke mage, then you don't really get much from it (except the fact your can just keep walking around to charge it easily).

This is what I would really like to see out of the Luden's charge rate...

Each spellcast and spell hits (and only one hit per spell counts to this) charges Luden's Echo by 5. If a target hit is a champion or monster, double the charge gain (meaning you get 20 per cast if you always hit a monster or champion). This tones down Luden's pushing power (as it now only will have the new functionality of 10 charges gained instead of the current 20, like what you all have changed about it recently. If you 100% whiff your shot, or it is a team targetted buff, it only charges by 5) and it tones down the ease of poking with it, without hurting it's use on rapid fire mages (assuming you actually land your stuff, anyway).

This is just what I would prefer personally, as I like the new Ryze (who heavily enjoys the high charge rate from spellcast, but almost gets nothing from the mobility part of Luden's charging) and it keeps Luden's charge rate in what I consider it's "optimal" use case of where you are always attacking, and more importantly, landing hits on, the enemy to keep the charges coming. Hell, I'd even be happy with Luden's Echo being divided into two items, one for poke/mobility mages, one for Machinegun/high cast rate mages, with two seperate charge mechanics while sharing the same unique passive (to prevent stacking them). Perhaps an enchant for Luden's Echo? You build the item and it's flat out just 10 charge per cast, but you can enchant it to have the poke mage or machinegun mage focus of power?

I don't know just please, Riot, leave something for the few mages who are NOT able to zip around the map at Mach 1 or cover half a screen in a second a way to use Luden's Echo please.
