Dear Turbine-
The time has come to where you must see about fixing the lag hitch whenever your UMD score changes via skill item or charisma modifer.
With the new epic destiny abilities that move your ability scores up and down depending on your current health, the frequency of these game hitches has gotten completely out of control.
It's really never been acceptable that we had to endure this...ever, but it has truly reached epidemic proportions, and is massively detrimental to the gameplay of everyone who has to go through it.
It needs fixing. I don't honestly care what the process is to go about it...you could even generate a lot of good will with your playerbase by making it so UMD'd equipment didn't de-equip when your score changed, thus removing the need to constantly recalculate it. That would be my first choice, but honestly anything that gets rid of the lag hitch will be acceptable.
