I think (e.g., my wild hair guess is...) the answer here is, some purple high level
weapons have multiple upgrade slots, some do not. Similar to the different dps
you can encounter for similarly named weapons.
I have a purple staff that allows haft/blade/rune additions. And another purple staff
that is one level higher, with more dps, but only a rune slot. The lower level staff
is better. So further RNG. You ideally want a high dps max level appropriate
weapon with all optimization slots available.
OK... but that makes zero sense from a game design perspective. A basic item should have minimal upgrades. It's a rusty sword, a branch from a tree, whatever. A unique item simply by its rarity should be more upgradable than that rusty sword. Just saying... we all want a game that makes sense...
Ah, I see my error here was giving too much information. I simply should have said I found an issue to avoid inevitable amateur design discussions. Also personal note - remember forum users will quote your private messages
