Most challenging and wanted DPS class?

[Shiroe]

drg is imo the easiest melee to play

nin has a lot to look out for too, besides the "core" rotation..

shinryu doesnt have postionals, so its not a good comparison for melee..
... personally dont find sam that difficult either, but maxing it isnt that easy compared to other melee (still do a lot of damage when playing average, but sometimes also due to getting all the raid buffs)
