I don't know if this has been posted here before (at least, could not find the information by forum search), but I've faced several rather puzzling things when trying out Firebird set. Are these known bugs or is everything "working as intended"? I enclose screenshots of several buggy situations (under spoilers).
1) Sometimes when an Elite is Ignited I do not gain damage bonus from Firebird stacks. As you can see, Butcher is on fire and my toughness is considerably increased due to that, but Firebird icon is not displayed in buff panel and I had to spend almost 10 minutes killing him on T7. RoRG was cubed, that's why I only wear 5 FB items.
2) Sometimes both damage and toughness buffs fail to activate upon Igniting an Elite mob. This time I had all 6 pieces to prevent possible conflicts with RoRG.
3) While damage reduction buff is supposed to work with 6p bonus, it is nevertheless activated when only 4 or 5 pieces are equipped (no RoRG in cube during this time). It happens really often and sometimes even FB stacks are displayed in the buff panel for a second (never was fast enough to get them on a screenshot). Yeah, it is good to have damage reduction on 4p instead of 6p, but it is in contradiction with set bonus description thus should be considered a bug, IMHO...
What do you think about it? I, personally, don't wanna find myself without damage and toughness when fighting Maltael on T13 or Rift Guardian in higher GRs on HC. Has it already been reported to Blizz or should I create a thread at official forums?
