Okay a general question to the masses for discussion.
With regards to advanced classes in TOR, you have two skill trees specific to your advanced class and one shared.
Do you think it will be viable to specialise in the shared trees?
Which means you are picking your advanced class on asthetics and secondary skill trees.
For instance I intend to play Bounty Hunter at release.
Advanced class (at the moment) will be Powertech, because I prefer the one large blaster and heavy armour
over the two blaster/ medium armour approach.
Yet from the basic information provided I am seriously considering specialising in the shared tree (Firebug)
over a class specific tree.
With regards to differing builds, most modern MMOs encourage this specialisation approach,
although I may be tempted to go hybrid for levelling and respec at end game,
as the word on the forums seems to indicate that dual specs will be brought in after release,
which probably include a free respec.
I remember in Neocron that a hybrid monk was actually a valid build initially, until later nerfs demanded you specialise.
