First of all, thanks a lot for the recent communication on all this ! It's amazing to get so much info from you guys !
Regarding the Aurora/Vision/Coalescence triple effect... Would it actually be such a bad idea to change the visual effects of the trinkets ? If it allows you to not have to put in a significant engineering investment ?
I know it's a matter of taste and completely subjective, but my personal opinion is that this stacking effect wasn't great to begin with, and that the final effect with all 3 combined is very very ugly. It looks like crap and even with how cool and convenient the Legendary Armory will be, this ugly effect is dissuading me from actually crafting & wearing more legendary trinkets.
On top of that, getting the same "Aurora" effect no matter which of the 3 trinkets you have equipped makes Vision and Coalescence feel less special.
Again i know this is subjective, but i'm also curious to know if there's really that many players who really love the combined triple effect and would be sad to see it change ?
