Kinda new player with questions.

For general info: I played the global test punch and bought the game a few days ago and I wanted to ask what changed since the test punch, in particular:

•Anything new added to the game? (Besides the new character)

•Are there any events similar to Splatfests?

•Did grabspamming die out? Please tell me there are no grabspammers anymore. After a few rounds online, I now know it still exists. On a side note, can you report players?

I would like any general tips too.
