I have read almost all of the posts on this board and I feel I need to put in my two cents. I play this game for the assassin role and would quit if it was changed for the worse. I have played every assassin in the game and I believe all assassins can be cancer, but they all have there weakness. I started in season 2 and was a mage main to start but fell in love with the deletion process. Started as Akali went to Kat and finally Evolved into Diana who I spend 90 percent of my time playing. I honestly love this game, I have never played another game as much as I have league of legends.
Akali- levels 1-5 is hell on earth, she is not at all easy to cs with if the person has some kind of poke.
Kat- very weak at the start of the game, Poke her down, force her to not be able to engage. CC her ult.. COMMUNICATE WITH TEAM and Don't Let Her Roam for free. Pantheon went mid and ate my lunch one game so bad I will never forget that game.
Fizz- Has a hard time clearing CS imo, watch for his level advantages and power spikes. Dodge (if you can) the drop on playful trickster.
Zed- Can be hard countered by Zil, Aniva, kayle, kindered. I feel zed is much more balanced after the nerfs recently. Give him nothing, back when you think you are low. Still hate his kit and I still hate dealing with that champ.
LB- hard time with wave clear and against a lane pusher will be forced to use abilities to cs. She will almost always be aggressive. Play safe until you can grab a negatron cloak.
Diana- Missed Q pretty much equals no engage. Especially if they dive in thinking the Q will hit and it misses then its death...
Talon- can engage hard but has no way of getting back out. If he thinks he can all in you then maybe you have stayed to long..
I could do this all day, if you get tilted go watch some videos on how to improve against a certain champ, go play that champ. Learn there cooldowns, learn the damage spikes so you know when to watch out for there engage.
Communicate with team, CC,dodge skill shots or find a way to survive the burst normally will send assassin's packing every time. Another idea is counter build them right out of the gates.. two rings into Seekers arm guard hurts zed bad. Summoner spells!!!! Take barrier, heal, teleport and exhaust is like the bane of a burst character. Crowd Control...Crowd Control... Crowd Control...
Every champ has the potential to deal insane damage in the hands of the right person. Every champ can be cancer.. You guys that hate assassin's with a passion, well I hate tanks with tons off CC that make my life hell.
I honestly have no sympathy for ADC's at all... The buffs to ADC's this season was out of control. I love eating your souls and I never feel remorse.
Mages I understand your pain, I personally thought the mage update and the itemization they came out with was not satisfying at all. Slapping CDR on everything felt extremely lazy to me. It lacked the WOW factor of the ADC changes and Juggernaut changes.
Supports, the day will come where they hopefully won't just band-aid your class.
Good luck in the rift.
