Your WoW analogy is WAY off base. Having played WoW also I can tell you that hunter/shaman (per your initial example) do not share the same storyline, core abilities and a talent tree. NO, SWTOR ACs are NOT the same as WoW classes, not even close, BH ACs are MUCH closer to being WoW buids, such as Paladin dps (Ret) vs. Paladin healing (holy). The different WoW class builds share the same storyline, core abilities and talents. So your analogy is wrong, and just as WoW allows multiple builds, SWTOR should do the same at the core class level. All of your other arguments are void if WoW can allow folks to play as dps, healers, or tanks at will based on an instant respec, then SWTOR can do it too.
