Did a quick check to make sure the new changes are live, and they are. So I'm headed to a dummy to do another quick test. Will post results shortly.
Edit:
Good news, people. The changes were actually fairly significant. The first thing I'll point out is that LB makes up a much larger percentage of our damage now. Mine is sitting at 30%, with LvB at 42%. What this means is that our sustained DPS during the periods outside of ascendance are going to be more predictable and consistent. It also means that if we have to stop or forgoe casting a LvB because we have to move immediately, our DPS will not suffer as large of a hit because the moving LB will do more damage than it did before.
The second thing is the numbers in general. I pulled 102k unbuffed on the dummy (and actually had to pop BL mid-ascendance because I'd changed a keybinding and popped SR instead of BL; not a big deal, but a small loss). That's very close to our theoretical max DPS on live
fully raid buffed. 102k is a nearly 15% overall increase from my live numbers, which is pretty phenomenal. It's exactly what we've been needing and asking for. It's an 8.5% increase from the last buff that they gave us. Not only that, the current T14 pc buffs a spell that is a fairly low percentage of our damage (around 7% on my test with the 4pc; probably around 4% without). The new T15 4pc buffs what is arguably our highest contributing DPS spell in the game, ascendance. It can only get better with the new set bonus.
I told you guys we were gonna be good this tier.
