Starting a new thread for this stuff. Here's the link I pasted with the talent trees:http://biowarefans.com/2011/09/star-wars-the-old-republic-talent-calculators/
One interesting thing is through reading these, there's a bit of insight into the resource models the classes will use. The jedi/sith guys seem to rely on force and the smuggler/agent guys on energy. These seem fairly normal.
The smuggler/agent guys both have a lot of abilities reliant on cover. This is interesting since it means their positioning on a lot of fights will be limited. It's an interesting idea but I'll be curious how well it plays out. If things get hardcore and they design a fight without cover I wonder if it means "Bench your agents/smugglers" or make them healers.
In addition a healer with an energy mechanic would be odd. Healers in WoW are balanced around having a large pool of mana that can run out. If, say, we had a rogue spec for healing that wouldn't be an issue. They could heal endlessly but would have limited burst healing compared to mana healers.
Bounty hunters seem to have a heat mechanic. It sounds like using abilities generates heat and you'll need to 'vent' heat on occasion to use more abilities. It feels a bit like a reverse fury mechanic.
Republic Troopers have power cells. These seem like they'll behave like DK runes just without being segmented into different types.
...note this is all pure assumption here.
