How do people like new Arena?

I am interested in getting a general opinion, because my experience so far was that it is more fun for casuals, but just thoroughly unenjoyable to grind rank compared to the previous edition. The added players and variety make it feel like instead of playing around gates, plants, revives, map, itemizing etc., you are just praying for a good prismatic and late-game matchup. Too often games go like "either we one-shot this guy, or we are out", and order in the top 4 seems to be determined mostly by luck.

Am I just too pessimistic in thinking the old Arena was way more skill-dependent? Maybe that is the goal with the gamemode?

Edit: I am glad people mostly agree and it is not just me. They tried for a more varied, casual gamemode, but losing is just never fun. So casuals complain about tryharding, tryhards complain about the much worse RNG. Balance, Koi Pond and Jhin all suck.

Also, I love arena. It is basically the only mode I play when it's out. That is the main reason I feel sad to see it being frustrating to play actively and being shifted from a skill-based gamemode to a more casual one.
