Skarner depends on his team now, how will he be after the update?

Skarner depends a lot on his team, and he certainly can't go 1v5 and carry games like a vayne or tryndamere. He's a great champion who needs a team in order to win games, without a team following him up he won't win you the game all by himself. I used him a lot before the mastery points came up, im level 4 on him now. I know for a fact he needs a team there and you need to be there for them.

With his new passive, he won't stun players anymore with the 3 stacks like before. Now you have to capture " crystals " in order to benefit from his passive. In order to do that you need to capture them yourself, or your team can do it for you. BUT, how do we know we will get players who care enough to capture those crystals FOR YOU. what if you get trolls or people who just don't care? will this hurt skarner? what if you're too busy capturing crystals making you have less time trying to get your essentials to be a presence in the game?

I compared the new and the old skarner, tbh im not even sure if it's a good or bad thing. All i know is that they completely changed his kit, his stun is now on his E and it only lasts for 1 second or so. There's some hybrid damage going on as well everywhere.... his W seems to make him faster but doesn't last as long.

Will this be a NERF or a BUFF?
