Advance Class Change: Good or Bad idea?

that is what we are saying you are trying to fit things to your point of view which is wrong. When you logic is applied to something you say its wrong... That is because you logic is incorrect.

Vanguard is a different class then a commando. Bioware has said this there is no point in trying to say it is other wise but you keep going regardless of how much proof is given to you. That makes you ignorant.

Why must you keep calling me names, does it make you feel superior?

Aside from "spec" and playstyle, what makes a commando so different then a vanguard that declares them completely separate classes? Why is it so much of a stretch that a vanguard cant decide to pick up a heavier gun and stay back and do further away abilities or decide to practice the field of medicine vs being a punching bag?

They do that because they do not have anything more valid to say on the subject....

Peter, you are doing a GREAT job.... keep up the good work.

the specs and play style is more then enough to make the different classes.

When one CLASS players totally different from another CLASS they are different CLASSES.

Aside from spec and playstyle, what makes a Sage so different then a Guardian that declares them completely separate classes? Why is it so much of a stretch that a Sage cant decide to pick up a heavier armour set, or a Guardian to stay back and do further away abilities or decide to practice Seer while the Sage can begin being a punching bag?

If they truly saw Commandos and Vanguards as completely different classes they wouldn't share as much as they do in this game.

I know I replied once, have more to add, this is from the actual swtor site.
Consular:
In a more peaceful age, Jedi Consulars may have humbly dedicated their lives to service as keepers of Jedi lore or as ambassadors in service to the Republic—tasks for which Consulars are uniquely qualified. However, as the shadow of the Empire has spread further across the galaxy, Consulars have stepped up to face the darkness on the front lines of battle as often as they’ve faced it when exploring the mysteries of the Force. The Consular’s powers go far beyond meditation and mediation, and nothing illustrates this as vividly as their graceful movements in battle. Whether beset by an army of assassin droids or caught in the middle of soured negotiations, the Jedi Consular fights with an open conduit for the Force; manipulating massive forces to disable or even destroy their enemies.
Knight:
The Jedi Knight’s graceful movements are awesome to behold. Freezing a moment in this display captures the deep commitment underlying the Jedi’s dazzling abilities. Though a Jedi Knight’s life is filled with battle and adventure, the Knight’s heart is dedicated to peace and service. An ironic observation to some, but greater wisdom suggests it is the Jedi Knights’ humble devotion which makes them so likely to become such famous heroes. Whether defending allies by deflecting a barrage of blaster-fire or charging in to challenge a Sith Lord, the Knight’s role is crucial in any conflict. The Jedi Knight enjoys the benefit of ancient teachings that have been passed down through hundreds of generations. Combining these time-tested maneuvers with the natural guidance of the Force, the Knight is capable of achieving extraordinary feats.

What is the difference between a vanguard and a commando again?
