Irrelevant bonuses.
Gauntlet thrown.
I meant irrelevant to the 2h crit build, not overall. They have their merits.
I prefer feat focused classes for the trickster due to the large amount of feats required, but then again you can always build the character without vital strike or weapon specialization etc. so Bloodrager or Magus will also do, probably better with some fighter/slayer dips to compensate? Magus Vital Strike with perfect weapon was already a thing back in PF, it could be very strong here as well.
Someone listed the unique weapons here :

The only 18crit 2hander with the increased crit multi stat is a fauchard, so I guess that will be the weapon of choice. Having so much crit chance makes crit multiplier the best stat on weapons.
