A question about base stat boosts from Runes Reforged.

First, we plan to directly change champion base stats. We’ll give every champion in the game an offensive boost tailored to what their kit needs. This ranges from attack speed on Tryndamere, Master Yi, and Yasuo, to starting ability power on Ahri.

Does this mean there won't be any defensive boosts to base stats? I don't want to live in a world where I have zero bonus defensive stats against an Assassin, especially one where new Duskblade exists.
