To Riot, Will Runes still be strategic?

Some may disagree with me on this, but personally I thought runes were very fun, and interesting to plan out. Sure the IP was a pain in the ass...okay a huge pain in the ass..

BUT!

To me it was super fun to have all these different runes, and set up combination, to plan out every season what the most effective runes would be. Hell I find it enjoyable just to go to my rune pages, examine them and check if their is a more optimal combination even though I probably already have it to the best performance it could be.

To me masteries were always boring for they were always so easy to figure out, runes always had a sense of complexity to it. However when I saw the video it looked like you were completely removing runes and simply buffing masteries. I really hope this is not the case for frankly the mastery system is pretty simple to figure out, even key stones are easy to figure out.

That being said, I am excited for the new system but I hope you guys don't dumb it down to much.
