Soraka - E snare
It's one of the most difficult snares to hit, unlike Morgana's or Lux's "juke half of your HP"-snares and yet it only lasts half a second. Everyone can walk out of the silence circle without boots in time for the snare to not land.
Also tactically placed E's that actually hit, like when you run away from a group, are pretty much useless since as Soraka you will still get caught because the snare time is just too low to compensate for her standing still and doing the casting animation.
A 3 second snare instead (LIKE MORGANA'S OR LUX'S THAT ARE MUCH EASIER TO LAND HINT HINT HINT) would work much better and make her E be useful for a change. And it still would be as difficult to land as it is now, except that people who don't bother walking out of the circle would actually get punished for it. The fact that it is AOE doesn't matter much, since people are to avoid the circle, which is super easily done without boots.
A microsecond snare just doesn't do the trick when casting her E is a longer snare for Soraka herself.
Either that or give us back her mana heal pls.
