The absence of RW from regular PvP activity is definitely a big hole. I'm assuming they will be addressing that, as last we heard they were saying something about bringing Astragalos back. Doing that will give players a nice array of PvP content to choose from.

I'm still amazed we don't have any Capture the Flag modes. CTF is one of the stand-bys of competitive games for good reason. Murderball is another really popular mode that is strangely absent.
