Immobile champs need changes to adapt to the mobility creep in the game

All. Of. Them.

It's become so infuriating to play against something like Yasuo or Fizz as a champion like Xerath or Vel'Koz. You have to wrap yourself around your turret to even have a chance in a fight, and even then they still stand a solid chance of killing you unless they suck. Once a mobile champion can catch you out, good luck.

Champions like these have had their damage, etc. buffed in the past in an attempt to compensate, but all this has done is increase the matchup disparity. Vel'Koz has like 10 champions against whom he doesn't have a prayer of winning lane, unless the Vel'Koz is literally Faker and the other is bronze 5. They need something to make these matchups more bearable. Not just damage. They need, on an individual basis, to have a serious look taken at them and to be changed in some way to make these matchups make more sense. Having counter matchups is fine. Having enough hard counters that are super unfun to play against that you feel like you need 15 bans yourself just so you don't lose lane in champ select? That's not okay.

I have a couple champ-specific ideas to make these matchups a little more bearable, just as an example.

Vel'Koz - E - Tectonic Disruption

Tectonic Disruption is changed to a dash-sensitive trap. When a movement ability is used on top of it (excluding summoner spells and ultimates) the trap triggers prematurely. Also, the trap is changed to a true knockup and cannot be reduced by Tenacity, etc.

We're going to need compensation nerfs for that, so let's revert the Q buff, taking its AP ratio back down to 0.6.

Xerath - E - Shocking Orb

The times when this is most wanted are the times when it's least effective, since the stun duration is super short when it hits a nearby enemy. Minimum stun duration: 0.5 --> 1.0. AP ratio: 0.45 --> 0.35 to compensate

These are examples of how I would make some of these changes. They're just placeholders, though, and not the core of my ideas (because they probably suck and are unbalanced). Any thoughts on this general idea?
