I find is interesting how many people seem to jump on the "nerf" bandwagon. Everyone seems to agree on a few champions that either need small tweaks or are generally balanced and then they just spam complaints about how poorly this game is balance. Then, they refuse to look at both sides of the argument because they won't let themselves be proven wrong. An example of this is how people get so worked up about energy champions. yet there are resource-less champions like Gnar who can be just as much of a menace yet has nothing to stop them from using their spells off cooldown.
In the case of Zed, at least he does have to be somewhat mindful about using abilities. For example, if he uses his spells to waveclear, then he will not have enough energy to fight, whereas champions who use no resources can do whatever they want whenever they want. This is my point on how people love to join together and complain about a problem while they don't actually think about their arguments.
And look at the comments that get downvoted. They aren't the troll comments that ruin discussion but they are the comments that argue the opposite side of the argument. So many people instantly downvote anything that doesn't align with their opinion and they refuse to actually discuss about what could be done, and I have no doubt this post will be downvoted to oblivion.
One other thing I find interesting is how people also complain about using Reddit compared to Boards, maybe it is because on reddit people actually attempt to understand what other people's arguments are. Instead of barraging the comment with downvotes.
