So Kass got hit pretty hard, mainly his Q not silencing anymore. But then I still think his kit overall is very good. Q + E damage got nerfed but with your W getting a pretty boss mode auto attack 140 (+.6ap) at lvl 5 AND restores 40% of his max mana on champions. Dafk? Plus, his Ult is now on a 3 second CD at level 3 instead of what it use to be at 5. You thought it was hard to catch kassadin then, it'll be impossible now. So with 40% CDR, which let's face it most APs get a CDR item + blue buff which gives them close to max, means his ult is on a 1.8second cast. Kass ult...every 1.8 seconds? Really? Plus his auto attack range went from 125 > 150, which doesn't seem like much but it's actually huuuge. So basically, he'll activate W, ult in, Q+E you, and auto attack you once and by the time all that is over his ult will be back up. Plus you get a shield that lasts for 1.5sec with his Q now, so it's "extra" tankiness. Yeah sure, he doesn't have a 2.5 second silence anymore but god damn his kit is still strong as shit imo.
Annie buffs are cool because it's a nerf to support annie but doesn't really affect mid annie. Although lately all I've been playing is Morg because she's basically OP as hell at the moment. Plus her build order is perfect since you get your frostfang > sightstone > chalice > mikaels. It's perfect cuz you get all that extra money from frostfang, get the free wards from sightstone and when you get chalice you can spam your spells 24/7 and finally another 600g later you get mikaels and between your root, your ult, your black shield and mikaels your ADC just can't die most of the time.
Elise still strong as fuck. If anything she got buffed. Her early game damage and clear will still be fine but now lvl 5 E is a 2 second stun (.5 sec longer) and her Rappel comes up a lot quicker.
TF will be interesting although yeah since you'd usually always rush Lich Bane if you could it probably just evens out.
Vi changes will do nothing. She'll still be a top ban/pick everygame.
All the other champs I don't really play much so /shrug.
Wriggles change still doesn't make sense. Giving AD is nice but AD + ATK while nerfing the gold income on it. Meh, still useless on 99.9% of junglers. If anything they should just try something crazy like have wriggles increase gold from jungle monsters by 100% just to try to force players to farm the jungle. As of right now it's ganking junglers all day every day and even if Wriggles gave you shit tons of gold for farming, it's still a risk vs reward because the other jungler could be ganking and winning that way.
