I think the change that has me most worried next patch is

The rift herald change, champions like tryndamere and jax who just wanna sit top and push top all day are going to love this item and they are the absolute worst to play against. I'm gonna HAVE to deny the rift herald or else my top laner is fucked and even if I do get it it's not very good for me or my teammates who might be planning on grouping up.

This buff on the map just kinda enforces having a split pusher on your team to optimize the map.

And I like team fighting personally
