I don't really get the amount of hate the patch got...
I mean, if I look at previous x.35 patches we got :

5.35
  • Bozja (just the 4th reskin of diadem)
  • First step of relic (just tomes farm)
  • DOH/L relic tools
  • NG+ chapters

4.35
  • HoH (and that's it)

Diadem reskin #3 (part 2) came with 3.36 btw with MH event crossover trial.

3.35
  • Palace of the Dead (and that's it)

2.35
  • Crafter tribal quest

So... no X.35 patch gave that much.

If I compare we already got a new zone with island sanctuary and we also got a Potd to do.
So yeah, usually, X.35 patches are just those to introduce another XP grind for the x1 to (x+1)0 levels.
Potd, HoH, Diadem#4, and in this case Palace of the diadem reskin#3.
And we also got crafter DQ around the same timing as the other era.
And the 2nd step of relics.

Nothing unusual.
