Random suggestion to open more variety in Seals (yellow runes)

The armor is pretty much used in literally everything. Like. Everything. Every build for the most part unless it's a super specific build, is going to have armor yellows. All the other runes are open to some type of variety. MR Blues, AP blues, CDR blues etc. The problem is, that little bit of armor you get from the seals make such a massive difference that it's pretty much almost mandatory that you run those yellows.

So my suggestion would be to just give every champion the +8 armor your get from the armor seals and removing the armor seals altogether, that way you can add a little more variety. Like Gold Seals, or AP, or health or whatever.
