I'm really done with every second thread being a complaint.
And it's usually already been said a thousand times. The balance team isn't blind. They're not incompetent. Changes will be made.
Sure, Lethality is pretty strong right now. The so-called 'assassin' meta isn't particularly fun for a lot of people. But guess what? There's been a lot of really shitty metas and there will be a lot more.
The only issue I have with LoL right now is snowballing. And that's largely because Riot added First Tower Blood - a truly stupid mechanic. Winning lane already usually meant FB gold + tower gold + dragon and a mid siege.
Teamfights are quicker now because people don't just group and crudely run at each other anymore. Players pick fights and then execute them as cleanly as possible.
Right now we're simply in a meta of front-loaded damage. You're not going to see prolonged fights like this if teams consist of a bunch of champions who excel at instagibbing someone but can be instagibbed just as easily.
Mark my words, soon enough we'll be in a meta of sustained damage and prolonged teamfights and people will still be crying about Caitlyn/Vayne/Jinx/Sivir/Kalista.
The fact of the matter is that some metas simply don't fit some people's playstayles or champion pools. They complain, and then everyone else starts complaining without fully understanding what's going on.
Just fucking grow up. Apart from anything, Riot it's a lot more likely to listen to one big thread with a billion upvotes and meaningful discussion than they are when you just got dumpstered by a Graves and decided to construct a poorly written rage thread that doesn't even address the actual issue because you only know that a champion is strong and not WHY they're strong.
Not to mention that, statistically, something like 2/3rds of these threads are being written by people gold and below.
