Assassins
First off, this isn't a troll post just to piss off assassin mains. That isn't my intent. Please actually read the entire post before replying and reply with good arguments not the QQ you just suck posts.
Having played over a thousand games at this point, it is painfully obvious that Riot needs to do something about the assassin class. They either need to be converted into mages or fighters or they need to nerf/rework the entire group. The assassins role is to take out carries, but when you have every assassin in the game able to delete tanks 100-0 before they can even get a chance to itemize, you have a problem. I see it happen in over 90% of the games I have played and watched. Assassin gets early kill, snowballs out of control, then completely dominates until very late game (which usually doesn't happen since the game usually ends before that point). I see this at pretty much every level of play except the very highest since they actually know how to not feed and get quality assistance from their team.
I always hear the CC argument. When you HAVE to use hard CC to stop a group of champions, that group is broken and that's why there is so much toxicity whenever the class is discussed. Of course CC works. It works on EVERY class, but other classes can be beaten in more ways then just CC.
For example, if an assassin is going to beat a tank, the assassin should have to go in and do their burst. Then retreat/kite away to wait on cooldowns, then re-engage to finish them off. If they just stand toe-to-toe with the tank, they should lose every time since the tank should always win the war of attrition with steady damage over time and high defenses. Unfortunately this isn't the case in the vast majority of match ups. If they are facing a carry like a mage or ADC, the assassin should be able to 100-0 that carry if they perform their combos correctly. That is their role and it's the tank/support role to peel them off to keep the carry alive.
So, in conclusion, I think Riot needs to find the spot where they can kill the carry in one engage but not any of the other classes. I think that would bring more balance and fun to the game. Thanks for reading and as always, constructive feedback is always appreciated.
cannot kill
cannot kill
(not easily anyway, she will probably die)
or will kill you even if you do
is an assasin. she CANNOT do shit vs tanks or burisers. and yet she gets nerfed because mages and adc's cant be bothered to step half in inch either side

are pretty much untouchable if played right, not only in lane but most importantly, in teamfights. Riven is very hard to gank, but in teamfights she can be CC'ed and shut down easily. It is much harder to CC a Fizz, LeBlanc or Zed.
