I'm worried about the Runes and Masteries update.

Note: This is an opinion and my honest feedback.

I play a lot of Nasus (Over 400 matches), and my current Runes and Masteries support me greatly. I start the game with 20% CDR along with some Armor and additional Damage. I'm worried that when the new Runes and Masteries appear, I will lose the ability to start with 20% CDR, it's essential to my playstyle.

I'm worried as a whole that for people who like customizing every detail, it will be more painful to have less choices.
