Removing Glacial Augments Active Restriction

Slows are not rare in this game.

There are no champions who value a slow greater than the current rune options (didn't check, but I would be shocked if GA Sion has a better winrate than comet or aftershock, or GA ASol has a better winrate than FFW/PR)

Instead, why not open up this keystone as a real option by removing one word: active.

Allow it to trigger it's slow field via Rylai's or Frozen Mallet, or Gauntlet. That would actually be a meaningful trade-off versus Kleptomancy and Summoner Spellbook.

Yet you start thinking about characters like Ezreal and I can feel some of you pulling away from me. But think about it: he'd be giving up klepto. This is what runes were meant to be, difficult decisions. Guaranteed effect via slow, or variably increased scaling from klepto, or HIGHLY variable impact via summoners (how often do great TP opportunities present themselves in solo Q aka the ward desert)

Whereas sorcery and domination are just like, do you want this dmg increase, this dmg increas, or this dmg increase on your boots?
