Not hurt by Tree delay.
I was working on getting all my Mechs to what others said is the needed XP amount for unlocking all nodes on the new Tree though I probably would not have the needed amount of CB.
I did get 1 King Crab, 1 Mauler, 1 Black Knight in the last sale and before that got 1 Cataphract, 1 Victor and 1 Quickdraw, none being chassis I owned. Figured with the new ability to not need 3 variants to Master, would be a good time.
None of this hurts me with the Tree delayed, still had a good time.
The Victor just did not work for me, I refuse to make it XL due to size (thanks Volumetric Rescale

) and STD does not mount enough weapons, sold it off though it did help with JJ testing.
Quickdraw is similar but not sold....yet.
Cataphract-0XP liked though the weaponry seems nothing more than a tougher Hunchback with ECM.
Black Knight was suprisingly enjoyable.
Mauler, tried a few meta builds, didn't like them then made one similar to the Champion coming out, did amazingly well even with Basics only.
King Crab, same as Mauler but I made my own build that works most of the time Basic'd only and got my first or second 1K+ game with.
A few letdowns, yes but not seriously hurt. Tree needs more time and refinement with proper PTS testing.
