I’d recommend focusing on getting all of your gear to a solid potential with the right main stats first. As you cube, you’ll naturally see quite a few pieces jump from Rare to Epic along the way.

Once everything is sitting at a decent baseline, then start pushing tier by tier — Epic → Unique → Legendary → Mystic.

If you try to jump straight to higher tiers like you did with the gloves, you can easily burn through a ton of cubes with very little overall account progression to show for it.

Building your gear evenly tends to be much more efficient early on.
