6link suggestion

I find it really annoying for me to upgrade my gems to 4-6 links then when I want to try to use new skills, I will have to upgrade them again. what I would suggest is to have the upgrade to be a permanent specific slot. For example, a character can have like 10 skills slot, we can make those slots unlockable by using the current jewelers orbs, that way we are not afraid to use them and can keep the unlock slots all the time. instead of being lock into a specific skill because if you want to change skills you would have to spend your jewelers orbs on them again, but then for a new build there are so many skills to be upgrade again. lesser and greater are only good for early games anyway then late game they are not as important, but then people will still use those perfect jewelers orb since u have 10 slots. if you make a new character you will want another 10 for some if they want 10 slot all 6 links. Hope you could consider thanks.

Gems (even with sockets) are tradable, so this is really only an issue for SSF. I dont think you really need more than 3 gem slots to test a skill. And if you need more than that, you probably already have a lot of your build centered around the skill you are currently using (making swapping it pointless).

If you are playing trade league, just sell the skill you socketed and didnt like.
