WHICH IS WHAT?! You said it was a different playstyle now you are saying its the same playstyle but played perfectly, which is it?
That is a lie, not once did I have DW lose RI stacks. Out of every single test I did not once did my RI stacks dip below 50% with DW.
And no, 2h will not have full stacks all the time for Obliteration windows. At least not all of them. Depending on when the stacks fall off, you could be going into a PoF window and have 0 stacks so you only get maybe 1-2 full stacked Obliterates. Even your opener it takes time to stack up RI. It lasts 12 seconds, it would take 10 seconds to get to full RI stacks with a 1 second GCD. That leaves 2 seconds to get one more Obliterate at full stacks.
So no, I will almost guarantee people will be on these forums complaining about how bad the tier set is with 2h.
