Assassin's Place on the Rift
Here is the answer to almost all of the problems people are posting about in regards to the assassin take over. What is an assassins job? To kill a target, ONE TARGET. ONE TARGET and they should be like, ok i did my job, how else can I help out.
Let me explain, should they have insane bust, eh yea to get in and get out, but really just straight up burst is for some mages and they suffer by having low mobility. Is their job to surprise and burst down their target, then have all their CD's reset and do it again to the next target, and then the next. Absolutely. An assassin sets up their kill, they plan it out, are patient and go all in at the precise time. If they mess it up they should pay the price, high risk high reward. If they do get the back line kill, then great you just turned the fight on its head, they have so much less damage now. SO DON'T LET THEM GO HAM AFTER THAT. I'm talking to you Rengar. ASSASSINS are NOT FIGHTERS.
RIOT UP THE CD'S SO ASSASSINS ARE ACTUALLY THAT, ASSASSINs. Right now they are fighters with the benefits of movement, stealth, and crazy burst. Please this is your answer, CD's. They get their target and then most of their efforts are spent.
p.s. the amount of cc is getting out of control in this game so please do what you have said you will in the past and make a QSS item for casters. Jeez, this stuff isn't that hard.
