Kneejerk reactions to Ekko's kit

Overall really fun champ, but as with all champion releases, there are some kneejerk reactions to some of the more powerful aspects of his kit. Here are mine.

2.25 second massive aoe stun as a level one ability. Yes, it has a long cooldown, and yes, it has a huge windup time, but 2.25 seconds on a huge aoe is just too much for a level 1 ability.. Start it out like Rammus taunt or Fiddles fear, ramp it up with levels.

His Q damage is too high at early levels. 120 with a .8 ratio at level 1? I know you've got to hit both parts, but still, you can possibly win the lane just with one lucky hit. Maybe increase the lategame but decrease the early, something like 50 for both hits at level one instead of 60, then at level 5 it's 130 and 170 instead of 120 and 160.

His base ad is 59 and scales to 110 at level 18. Doesn't that seem a bit high? Diana fills a similar role (but with vastly different kits of course), and hers is 53 starting scaling to 104.

And finally, this is something I'd like to buff about him. I'm not really a fan of the enemy knowing when my ult is down. I like how they can see where I'll end up, but I don't like that they know when it's on cooldown. I don't like it for Shyv and I don't like it for Ekko. I wouldn't mind at all if the ghost was up even when his ult isn't.
