Biggest differences i've seen for the warder is with the mobs.. current planet mobs never went near the temple so you could camp in certain spots as any class without being harassed.
There was also "temple guardians" that spawned around the temple too*, ~cl45 voltoi skin,
Warder also used to be vulnerable to explosive and res to other types.
*can't quite remember on how/where they spawned but either had poor scan or spawned further out so you could camp.
