The talent specialization allows the shot to really be a commando squad and concentrate on the latter, it high-power DPS by taking advantage of the brand assault gun. Regardless, I can not imagine that a specialization of scrimmage for the Trooper would have great talent, simply because it is an isolated tree, without natural pair. It might be interesting in PvP, especially for duels but if you can combine the capabilities of high-damage melee with the defensive capabilities of specialist skills and Shield Remote Assault Specialist (shared the talent tree). We will see soon enough.
It may be difficult to be a primary healer and he will certainly have some strong capacities if it wants to stand shoulder to shoulder with a class that has two casting talent trees like Jedi Consular and swtor credits in the game. The Commando class is certainly one that the players were really excited, but I think some of the excitement around this class has been hampered due to the announcement that this class will have a healing talent tree as one of its two unique talent trees.
However, to date for low-level PvP and so explosive, the specification of healing does not seem adequate. Whether or not it will pan to level 50 is another story. I think players should be able to match this just fine with the specialist assault (the talent tree split) if they want to play this class as a full-time DPS. It will be a viable class, but it is unlikely to have more than a handful of viable builds. I'm not completely sold on the tree Combat Medic - this is a unique healing talent tree all by himself.
The Bounty Hunter is a class that makes heavy use of technology, including blasters, flamethrowers and rockets, in order to do its job and buy swtor credits in the game. This particular class has a wide range of roles depending on the specialization you choose, some of which seem a bit surprising for the players. There are two unique talent trees available to the Commando: Gunnery and Combat Medic.
