Level Cap is now 55.
A lot of skills and their respective tress have been tweaked (some quite severly)
although the main skill in each tree is the same it just takes 36 points to get it.
A new level 51 skill for each class.
Another Tier of crafting.
Planetary Commendations are no longer planet specific.
etc etc etc
My biggest gripe is that they have removed multiple skills from every class, all the ones that require a stunned state
i.e. Savage Kick and Pommel Bash for Sith Warrior, Eviscerate and Head shot for Imp Agent etc etc.
The reasoning being that they are hardly used at end game, they do not work in PvP, most mobs in Flashpoints are stun resistent, skill overload etc etc.
Well I used them, as did many others, admittedly certain of my characters used them more than others,
but I enjoyed watching my Sith Warrior do acrobatics in Savage Kick and my Agent stunning, evisercating and back stabbing trash mobs.
If you don't like/ use the skills then remove them from the toolbar ratehr than reduce my playing options.
Now my rotation will be like every other Sith Warrior or Imp Agent.
I realise that chances are only a couple of people will read this but I needed to vent some heat (
