Idea for a new mythic item

HanYolo

I had an idea for a mythic item hanging around in the back of my head and always discarded it as unreasonable. But with the last batch of mythics in the High Isle DLC ZOS showed that mythics are not only limited to providing stats but are now also allowed to interfere with "base" mechanics of the game (for example: disable bar swap, change invulnerability of dodgeroll to a shield and so on). So my idea is this:

1 Piece: The ring adjacent to this ring counts as three set pieces.

This has a lot of implications. The ones I can think of are:
1. Allows you to play a 5 pieces on the body, one 5 piece proc set backbar and another on the frontbar
2. Allows for easy access to the PvP based 3 piece sets and the trial 3 piece bonus if needed.
3. Enables gear combinations like Monsterset/5 piece body/ 3 piece set rings/ mythic neck/ arena frontbar, arena backbar

It basically opens up a huge amount of build options you didnt have before. Any thoughts on the idea? Grossly overpowered or utterly useless?

as with most mythics, what would be the "downside" if the "plus-side" is basically getting an extra set bonus or 2?

im not sure i understand the effect either, if it just effectively copies the other rings set wouldnt it make more sense just to use 2 rings of the same set? and only making the other ring count as 3 items, your already losing 1 item from the mythic, so at best you would be gaining only 1 additional set bonus

2pc for monster, 5pc for another set, and front/back bar arena weapons your left with 3 slots open for jewelry, why not just use a full 3pc set there to begin with, instead of 3pc ring + this mythic which would end up leaving you with 1 filler hole anyway, would be better to use a 2 pc filler + almost any other mythic at that point

its an interesting theory, and i could see it being fleshed out more such as if you could use a 2 pc monster 2 5pc set and 2 arena weapons, but at some kind of cost or downside
