Heh the sarcasm went right over your head.
If anything, sith warrior is more like the wow warrior. Rage builders, rage dumps, aoe is very similar is visual style, cleave - sweeping strike, thunderclap, forget the sith warrior ability at the moment. They both have a charge, both have a kick, and stun, and an aoe melee range stun.
Inquistor (Assasin Spec) is similar to rogue (stealth melee class).
Bounty Hunter (Ranged specs) are similar to Wow Hunters (Channeled Shots, Instant Shots, limited constantly regenerating resource (focus) (heat, or lack there of) that you can rebuild with abilities.
Inquisitor Healing spec reminds me of Disc Priests in wow.
But I wouldn't say that any of them are copies. All of the SWToR classes feel like they belong in that universe, but certain classes lend themselves to certain play styles.
Played a stealther in wow? Probably want to try assasin.
Warrior/Druid Tank? -> Immortal Juggernaut
Ret Paladin? -> Venge Juggernaut
Fury Warrior, Dps Dk? -> Marauder
Hunter? -> Mercenary Bounty Hunter
Honestly the swtor combat system is very fun if a bit clunky and it has a little too much button bloat. They need to trim some abilities, and balance the abilities to use a priority system rather than a clunky rotation based system. I hate having to weave worse abilities before stronger ones so that the strongest ones occur in specific window to get max dps.
Maybe I need to practice until it becomes muscle memory.
