Weapon Upgrade & Infuse result in less Impact Bungie please take a look on this. I recently upgrade one of my 7 Treads Upon Stars to 310 and the result was really bad. So I decided to test all my Treads Upon Stars. By comparing all of them the only noticeable changes are Range & Stability; at least that the only red and green bar change. Look like with lower Attack and no upgrade you get higher impact. I made my test on strikes and mission hitting red, yellow and bosses, the result was always similar. I did the test with Goblins, Hydras, Cyclopes, Tankis Boss, tanks. For this example see the following stats I use a Redbar Centurion; head were critical yellow hits; while body were gray hits. Attack / 283 no upgrade / 289 no upgrade / 290 upgraded / 310 infuse + Upgraded Head / 1851 / 1591 / 1301 / 1301 Body / 911 / 911 / 456 / 456 How can you fix this?
