Since he's a melee fighter, how about he also reduce enemies armor by 2/4/6 per second up to 5 seconds, which he reduce 10/20/30 in total. He also gain 1/2/3 per second from each enemy champion who is standing inside the whirlpool. The stack ends when Ground Swell also ends.

He gain 5/10/15 armor from one champion who gain max stack from Ground Swell.

In total, he can get 25/50/75 armor when all enemy champion who has been standing on Ground Swell for 5 seconds.

Magic damage from Ground Swell can be reduced to 40/65/90 per second which in total can deal 280/455/630 magic damage.

Casting Hollow Scream inside Ground Swell will cause the circle edge of the cone create an impassable terrain (like a geyser or a big wave).

Those are just suggestion i came up. I got really surprised when you also thought that Ground Swell had directional MS modifier. (Just back then when it didn't show the ultimate.)
