Can we discuse the elepante in the room?

We need to start looking at all these champions that can 100 to 0 someone with little to no cost. They don't have long enough cool downs, they disguising if they if they land two abilities, or they can deal ton of AOE damage. , , any late game that adc can burst squish targets. Tanks that can do more damage with one ability than another full rotation. That is to say, while does way to much damage, at least it takes all of her abilities to make shit work. The only place wide enough for not get decimated if in lane, try playing a game without ever entering the jungle, it doesn't work. You'd need 5 to even attempt it which much success. To make maters worst, you HAVE to buy a against a but honestly, its a shit item. It's cost is INSANE for what it does, at least buff the AP so I don't feel crippled why I have to buy it. Any now, and , both of these items need to be removed for the game. They're too powerfull, and 0/6 can still one shot you (thou part of that is his own imbalance) with just that item. And has the opposite problem, 30% of damge is turned into damage over time. Anything that doens't have insane damge cannot one shot with full combo, but can be killed with two, or even just one ability. That is actually insane, have you seen with this item? God dam unkillable unless you've got crazy high dmage and cc, because you gonna need him to stay for a while, which bring a question, why doesn't have a raid boss skin? Items are completely unbalanced in how they scale depending on the champion, and the only ones that can shrug this off are meta champions. Now I'm not talking , yes that broken, but I'm talking two comparable champions, landing everything on each other. One can one-shot, the other needs two rotations of spells.
