The idea that you "dont need something" especially gear is a matter of opinion.
There are two reasons i can think of that you are wrong right off that bat. Gear progression in this game is fast paced. Even if i dont get this tome gear, a new gear will shortly appear from a new tome. Do i keep not getting new stuff because i dont need it and just wait till they are no longer capped? The situation would still be no different. I would be spamming stuff i dont enjoy to gear only without a cap. Second reason is since gear progresses so fast in this game you can fall behind and not have a high enough ilvl to do new content. I cant keep enjoying xtreme primals without gearing. Even when ex sep came out my ilvl wasnt high enough cause i lost interest in the eso system and had to catch up, it was made worse because of farthings.

Honestly just because i dont need it doesnt mean i dont want it. I like the gear, i like making my character stronger. What i dont like is the current means of doing so.

I'm actually fundamentally against weekly caps on anything anyway in a pay to play game.
