I agree, this is something that should be considered.
I love theory crafting and creating interesting builds. That being said, I’m extremely excited for the new trait system. However, the thought of having to make up the extra stats from traits with brand new gear is daunting. It’s taken me months upon months to get full ascended trinkets for my characters, it would be frustrating for them to become useless. Even having to buy/craft new runes can be a huge hit to players with multiple classes.
Until Anet comes out and gives us solid information on how this is going to go down, all we can do is fear the worst and hope for the best
