Except, tank items generally weren't built on squishies because the whole point is for them to be like a glass cannon and do damage, while the tanks and such would soak up damage and the supports would help keep people alive. Not sure why you're crying so much.
"I have no valid points therefore I will tell you to just shut up and get it"
ok.
Blue Ez was him abusing items that weren't intended to be used like that in the first place, weird builds are gimmicks in the first place, counter builds help deal with a champ, they don't /usually/ completely nullify the champ, anti-meta is anti-meta.
"we want it to work for us so if you don't like it, deal with it"
ok.
Sterak's is not OP as in the sense it's like the assassins or their items that help burst you down, but it is OP in the sense it denies things that legit should not be deniable, especially on squishies whose main weakness is the FACT THEY ARE SQUISHY. Sure, it allows you to survive, but you really shouldn't be surviving if you get caught out by an assassin in the first place, that's literally the whole intended point of an assassin. That's like telling a cook to not cook anymore because you want them to like, do industry or something instead, because you don't like cooks cooking.
Oh okay, I see the salt now. You got killed by Zed when you're a squishy. Wow, what a surprise. Sterak's isn't something like Zhonya's that makes you literally immune, it still has the potential for you to be killed, but if you two are anywhere near on even footing, it makes it ridiculously hard to do so. One single item should not essentially completely negate an entire class of champions for such a cheap price, that also doubles and lets you just keep fighting as long as the shield is up because bursting through it is also stupidly hard, like if I said, the two of you are anywhere near on even grounds. Your argument literally is worthless at this point.
There already are items to counter hard bursts, but given the assassin is literally meant to do just that, completely nullifying it like Sterak's does is stupid. Wow, you prefer to survive? I'm sure most people would. Guess what? Pro tip, don't get caught out by an assassin. If you would actually ward and not just leave your team behind, assassins really can't gank you that easily, because they're generally meant to obliterate single targets. Leaping into a team would be suicide. There is no "science" behind building Sterak's on squishies. It's a "let's make an entire class of champions useless because I dun wanna die" item.
If anything, people like YOU are the one who need to figure out how to ACTUALLY counter the assassins and not just use some bullshit item to completely nullify it. Assassins work by eliminating single targets with high burst, and are generally squishy themselves. Guess what, if you're a squishy, try... I dunno, not being just completely by yourself from mid/late game where you could just, stick with your team and then not die like that?
I find your last paragraph extremely amusing when I barely care for LCS or pro-streams or anything like that. I build items and champions in ways that maximize their efficiency, and occasionally I look through guides for champions I am new to/unfamiliar with so I can get a better grasp of things. Sure, creativity is good. This isn't creativity. I would suggest learning the difference.
"If it works, it works"
Except, it's something that SHOULDN'T work, and it works, because it's stupid.
But of course, this post will probably be downvoted to oblivion by you and all the other salty QQers who get upset about losing to assassins as a squishy and are like "omg broken pls nerf" because instead of actually figuring out how to counterplay and get around them, you'd rather just not use your brain at all and demand nerfs instead so you can feel better about yourself.
