Thinking about it more, i think getting rid of ancient legendary weapons all together and having this system would be more fun. Or if they want to make primals really that good, make them the only ones that can be upgraded.
So basically the system and random Korean/Asian P2W crappy mmo has with the whole +1/+2/etc?
LOL. Next suggestion would be for them to sell special reagents that negates the chance of breaking an item for real money.
I can see how popular a system like this would be with people having farmed so much for their well-rolled piece of gear just to see it destroyed by RNG.
This thing is as bad as Primals v1.
