The glyphs are definitely a fun idea to shake up the item builds but in its current state, this flaw is more than obvious. This goes against their decisions in the past seasons, like for example when they removed boots to prevent the exact same problem of "mandatory" items.
Adding only 5 glyphs seems like a mistake, either add to most of the items or to none. Personally, it's a super fun idea that should be expanded upon and not cut, but with how past unique ideas went, I wouldn't be surprised if it was cut from the game eventually.
