Luden's Echo Change

Id like to know ur opinion about a change I was thinking about. Since I started playing mid or squishies in general it's getting really hard to survive the 10000 skillshots coming in battle against mages and even when I manage to dodge abilities, a random skillshot will hit an ally or a minion and make me lose 150 hp for free without anything I can do to it, every, 5 seconds since the passive charges up super fast. SO I was thinking if riot could nerf OR make Luden's passive ECHO an active. So at least mages dont get rewarded for completly missing spells by still hitting 130-150hp (early-mid game it's still 10% of an adc hp or 5% of a bruiser/assassin that u cant dodge), u can even put it on a 30sec cd.

UNIQUE – ECHO: Gains charges upon moving or casting. At 100 charges, the next instance of ability damage you deal will expend all charges to deal 100 (+ 10% AP) bonus magic damage to the first enemy hit and to 3 nearby enemies, prioritizing enemies damaged by the ability and champions over minions.
