At the time I loved it when DX reunited (HHH, Road Dogg, Billy Gunn and XPac but not Chyna) on Raw in late 99 and beat down Austin and Rock. However when you look back now you kinda feel like all involved (inc Tori at a later stage) where presented as lackies for HHH (who was getting over huge admittedly).
As an old-school Raw fan I have two great memories before the Attitude Era too:
A young rookie named The 123 Kid (who would become Xpac years later) cleanly pinning established star Razor Ramon (Scott Hall).
Marty Jannetty returning and pinning his old tag-team partner HBK for the IC belt (which IMO meant so much more back then than the belt does now).
