Did we really need t3m4?

Of all the old republic characters we recieved I feel like the one that is the least useful is t3m4. Understandably the droid played a much larger role in the knights of the old republic games but in this game t3 lacks any synergy with any other toons except hk47 and that's just because they are both droids. Aside from being co pilot of the ebon hawk, t3 comes off like a severely lacking knock off of r2 possessing 2 zetas but since both only apply to droids this puts it at a great disadvantage and ending up being left to collect dust unless players use it on a grievous led droid team.
