Personally I like the new season.
One thing I really disliked about the past 2 seasons, is how it became a "one-shot" meta whilst snowballing recklessly was easy and keeping yourself present and alive at fights was less rewarded. Tenacious, and careful players just needed to suck lemons seeing their allies die over and over. Now playing the last few days, I feel the talent of keeping yourself alive is not only has the merits to dish out the pain (dark harvest resets), but also denies enemy income more heavily than ever. Maybe the "CS factor" needs to be toned down but still i quite like the direction this is going.
But again, killing that stray "I refuse group I CS!!!111" ADC is now way more fun than ever. Those sort of unskilled players that do not ward or listen to pings are just worth SO much cash now.
And another thing, I'm quite astounded how tanky the towers are early. I had a A-sol, lucian, brand on the enemy side bashing the tower and it still held more than I expected. It did not go down in one go! Yeah, I know they get some gold, but overextending is now another fun thing to punish this meta. I love it as a mid/jung player.
