lol azir is still buggy a year after release
hardly as much and it hardly deserves priority on their list of things to do, especially considering how much work it would take for a less-than-deserving and not immediately needed result. They only just got around to Yi which, if you don't code, was a huge project in itself.
it took a whole year for riot to realize people were quitting their game because of stupid DQ. after a year of complaints and a year of "deal with it" they found out even their pros weren't streaming their game and THEN decided to do something about it
simply not true, you can't just remove something as integrated into league as DQ in the middle of a season. The soonest possible time was for this next season
ekko's ratios on top of his mana costs were fucking retarded on release. his shield was stronger, his q did more damage, his passive did more damage, and his ult hit like a fucking truck.
it also helps that his ult was easy to land on players and his general kit was new enough to league where players took awhile to adjust and learn how to counter his playstyle. Ya, he was a bit overtuned when he was released (as customary for most champions because that's simply business, not a "i don't give a fuck about the playerbase" statement so don't be sensitive).
On vayne
you don't realize how fucking broken she's going to be after the assassin update. you'll see.
with what? If you're talking about the new Duskblade, you realize she has to stay invisible for the full duration of her Q (assuming there isn't a control ward around) to activate that juicy 50 true damage? That's hardly worth it considering how she misses out on 2 autos and possible a w proc just for 50 extra damage...buying that item actually is going to be bad on Vayne
