Runes Rework?

Runes haven't been touched since launch of the game. A few runes have been added since then, but everything remains virtually the same.

Do you (riot) believe you did it right at the start?

I haven't heard anything about runes rework. Is something coming? Have you looked at it at all? Is there any real reason to even have it?

There is a lot that can be done to make runes a little bit more exciting or interesting to use. Reworking the entire system seems like it may do a lot.

Currently, it is just an IP sink. To me, it just doesn't seem up to par in terms of attention/precision that all the other parts of the game have received.

I am just honestly curious if this is going to be reworked in the near future.
