DCs relating to Improved Trip - what's happening?

[Kamode_Corebasher]

Hello everyone... I've recently returned from a long break and the character I've built is struggling to land any improved trip in Legendary elite content.

Character is level 32 and all geared out ...improved trip DC's at 115 normally, and 125 when Action Boost Tactics is up. Could get it higher with pots, but...

So when running elite Sharn or Saltmarsh or Dread, I seem to be landing 5% of the time. What? Why? How?

And core 4 of FofW "Be the Whirlwind" isn't helping.

(I was excited with this build when mapping it out, very excited about the "Be the Whirlwind" and hoping that my feats spent on Whirlwind Attack would also apply an Improved Trip with core 4 FotW, but now that he's level'd I'm finding it a big disappointment)

Again, does anyone know what's happening with this? Any talk of fixing this or next steps in the Devs minds or ?
