The Ask Mr. Robot simulator is now updated with the latest patch for all DPS specs.
As I mentioned last week, you can verify all of the updates. For example, Fel Barrage is reduced to 250% AP. You can verify that on the spell wiki, in the damage section, the first number in the formula is 2.5, which is 250%.
Also, on the artifact weapon, FotI has been increased to 140% of weapon damage, also verifiable on the wiki in the damage section. The first number, 1.4 is the 140% weapon damage multiplier.
If you want to test out artifacts, you can easily edit them or add/remove relics in the simulator. Just click on any part of the artifact interface to change it - that easy. Here's a 1-minute video showing all of the character customizations in the simulator.
Edit: Wow, someone got to our wiki fast and said we might have the ICD for Fel Barrage too high at 1.5 sec instead of 0.5. So we'll double check that with some in game testing and update if needed. (Apparently the wiki does really make bug-finding fast!)
