Why is endgame loot capped?

[Mr_Gyactus]

I'm a new player and I see a lot of content creators discussing the gearing system and its problems, but It only makes me question "Why is the loot capped?"

I mean, in other MMOs you just farm the encounter until you get your full set, and here it takes weeks for no reason at all. We don't have any reason to do savage content multiple times a week, for example, or to farm Alliance Raids.

I keep hearing that Criterion and Alliance should give raid equivalent gear, and that's a good solution, but no one addresses the problem of loot cap.

With that being said, I'm still a (very) new player, so I'm curious to see what you guys have to say about it, because there must be a reason for no one to say anything about the loot lock and keep searching for a myriad of different solutions.

you can craft or buy all the high level gear you need, and this crafted gear it's enough for every live content.
Even the best gear you can obtain now will be useless in the next patch, in 2 months from now.

Where is the problem?
