So far, PSP2 is as fun as Kirk told me. I took my RAcast to the trial level cap (fifteen), although I've only leveled its job level to three (out of five). Then I started a HUbeast, which is only level four right now. It's also nice to see some of the unique things make it over to PSP2 from PSU and PSZ, and how some things have been improved.
+My Room (a carryover from PSU, fill it with unique mission trophies and decor)
+Weapon Grinding (no more grinders, no more weapon breaks, all it takes is meseta)
+Line Shield (now you're able to change it on the fly via a palette like weapons)
+Targeting (auto-tracking improved, L-shoulder button for reorientation; feels good)
+Customization (now it's more about the drops than what class you play)
+Online Multiplayer (PSP1 had no infrastructure, PSP2 has infrastructure and it's free)
+Status Effects (no longer attached to a particular element, totally random)
-Teching is tough (like PSU, techers are gimped again; toughest class to play as)
-No player economy (no big loss, hard part now is finding people to trade with)
