Anyone else feel the upgrade system reduces your choices?

I think the upgrade system is great but I have one quibble with the design philosophy. Mainly that being able to infinitely upgrade items means the optimal strategy is to invest everything in one weapon set and never switch up your playstyle. You can find unique or high quality items later you might switch to but anything you invest in those will feel like a dps loss. I think it would've felt better if there was some level gating on the upgrades that kept you from spending all your mats and let you have a roster of 3-4 weapons that were all fully upgraded to the highest amount for your level. Like say each quality tier had a level requirement.
