I have a sorc healer that i'm leveling on pot5. I have endurance crystals in my saber so what? +82 endurance on a lvl 10 toon scales pretty nice in pvp.
Since you clearly don't know what you're talking about -- he's saying that numerous people are putting HILTS (not the crystal -- you do know that crystals aren't hilts...right?) that don't match their stats.
Having gear that adds more endurance is fine, as long as said gear also adds to your main stats. A Sage in +str gear is being stupid, no matter how much endurance the mods add.
More galling to me is the number of people who have no clue how to use their abilities, one guy appearantly didn't know there was a skill tree in the game!!
