Ok I am bout to say what I think is op from looking at the patch notes. If you wanna ask why i believe something is op I will be on multiple times today to check this chat and explain my reasoning.
Champions:
Kennen(ult does a truck load of dmg now.)
Veigar(TOO MUCH DMG)
Velkoz(I already think vel is strong, this just adds to it. Look at my match history)
Syndra?(I think Bjerg and POE will like her)
Brand( Im gonna try to grind with this champ.)
Zyra
Cass
Vladamir?(he has really good dmg late game but has no cc. He basically a dmg dealing tank with less ways to heal imo.)
Viktor(practice makes perfect)
Zed?(you cant qss zed ult now)
NOTE: strong early game bot laners I think should be PICKED OFTEN(CAIT) so its easier to control dragon.
JUNGLERS WILL GAIN EXP MUCH FASTER NOW DUE TO JG CAMP CHANGES. PLS WATCH OUT FOR GANKS.
Good Items(op items included):
More champs will use tear
Catalyst( very good for laning phase, anivia, cho, etc. get buffs from this.)
Chalice( also good for laning, will be used more often now)
Morellonimicon(more of an item you will buy against the likes of vladamir)
Athenes(nice support item now)
Abyssal(I think this is staying in the same spot as a decent pick up for 99% of ap champs)
New Hextech items( One gives a escape or way to go in and one slows enemies to stop ganks or chase)
Bloodrazer
Buffs(what each do and their uses):
Earth dragon can help destroy objectives faster(dont forget baron).Its not the the greatest out of the dragons but dont underestimate it.
Fire Dragon gives TONS OF AP AND AD HOLY ****.
Cloud Dragon increases out of combat movement speed. Its good for early game roams, thats pretty much it. What you can do if your team is ahead and you have this dragon is to just leave it there and dont let the enemies have it so they dont get and thing dragon buff and u can scale to mid game.
Water dragon restores 10% hp and mana every 20 seconds. If you get this and lose lane you should go cry in the corner. I am sorry but this is like extremely broken in the early game.
If you controlled and got most dragons then Elder dragon is EXTREMELY BROKEN(increases buffs by 50%) If not then its the same as getting fifth dragon pre patch.
Rift Herald is like the ultimate gift to win lane. If you lose lane with this then I suggest you go talk with your doctor. THIS LASTS 20 MINUTES AND CAN STACK WITH BARON LIKE PLS DONT LOSE WITH THIS.(only spawns once)
Baron duration increased by 30 seconds. Hey, thats pretty good!
Blue buff and red buff extremely buff( I think its safe to say that every buff besides air dragon is op.
when a monster is gonna spawn in 60 seconds both teams will be able to see that.( dont be predictive with the order you clear your camps is why I think riot put this in the game).
