If they go through with the CDR Boot nerf...
To recover the 5% lost, I need to add a CDR quint (losing my movement speed one) and replace all of my seals with CDR (losing 13 armor, which is a sh*tload) because I already have blue CDR runes. Scaling CDR runes are currently extremely underpowered.
And the funny thing is I still will have about .20% less cdr than before. Even with all that.
