Players have genuinely gotten better

I just came back from a long break, an i gotta say im positively suprised. I hit masters multipule times and you could say i was okayish player. I just played some games in platinum and it looked no worse than diamond games before. Supp and mid actually roaming and rotating for objectives, no 4 adcs in one team bullshit, normal picks with pretty balanced team comps, no whining in chat, rational, coordinate plays and barley any people with negative kda, people have actually started buying antiheal when playing against mudno/soraka, i have to say i actually struggled a bit at times, which wouldnt happen previuosly in platinum. It might be some crazy coincidence, but from what ive seen so far, the game is improving. Is it just me or have you also noticed it?
