The "Reworking" trend.

all had winrates below 50% before being nerfed. winrate was above 50% with a fairly high pick rate before she got buffed heavily. Various patches such as buffing 's scaling occurred when he had a 55% winrate.

I realize winrate doesn't mean everything, but when a champion had a 45% winrate before nerfing the strongest ability in their kit, that doesn't give me hope. I tried out Ryze after 5.10 and he's still incredibly weak. I just don't understand the balancing team's logic. Buff a champion when they're already strong and popular. Nerf champions that already have enormous tradeoffs (Veigar Ryze and Kassadin all had weak early games in exchange for strong late games).

Are we going to buff Riven Leblanc and Fiora next? Nerf Elise Syndra and Azir?

tl;dr I'm asking for more common sense when you completely change a champion's identity. If you're going to adjust a champion's strengths, make sure you balance it enough to where they are still playable.
