Make/Add Grounded as a Summoner Spell
Ignite to counter healing.
Exhaust to counter damage and MS.
Barrier to counter Burst.
Heal to bait for dives and to counter running out of HP.
TP to counter/enable splitpushing.
Cleanse to remove debuffs (Owait lol. Why use Cleanse when
QSS exists? Summoner Spell>1550 Gold)
Smite for securing jungle. {{summoner:2}} Clairvoyance for extra vision.
Clarity to make up for wasting your mana.
But not a damned thing to counter Flash/Dash/Hops.
Adding this can blanket-nerf mobility creep, which now dominates our stagnant marksman-centered meta. You'll see mid laners who aren't Zed/LB/Ekko. Junglers can now actually gank these incredibly safe picks. Flash may no longer be a 100% pick rate summoner spell. Maybe there will even be a Red Appreciation Thread. Haven't had one of those in a while, eh?
TL;DR: Grounded should either be applied via Exhaust, or be made into it's own spell. As of right now, there is no counter to Flash/Dash/Hop abilities, hence why these champions remain strong even if stat-wise, they're middle of the pack.
