There are definitely good and bad things about SWTOR.
I like
1. Questing (for now, it will probably get old when Im on Xth alt, right now have only 2 50s and one on the way)
2. Space missions (obvious have alot of room for improvement and more than 5-6 generic missions with different planets in the background)
3. Environment, the planets look great, there are few exceptions like Nar Shaddaa, which is loathed by many, but its different for everyone, I for example love Belsavis and hate Voss, while friends have it the other way .p
4. Professions
5. Class differences and resources (heat, force, etc)
6. Flashpoints are reasonably long, some are pretty fun, it will probably get boring after a while tho
I dont like
1. Major bugs (ability delay as a top one)
2. Too many, often redundant abilities, abilities that dont work in PvP, even when conditions are met (stun/slow etc)
3. Too much sharding and phasing, I barely see anyone on the planet, or barely come across a freshly killed boss for bonus Q, because they are usually phased out. Which goes together with...
4. World PvP. There is barely any. From what I saw thourgh leveling for both Emp (2x50) and Rep (35 so far), the planets are just completely different phases with same layout (Balmorra, Taris), different layout, unaccesible by the other side (Nar Shadda) or questing zones are for 90% different for both sides (Tatooine, Alderaan, possibly others) It might get better around Belsavis and later, but I have yet to see it. I think I saw 5 republic players on Voss during my time there on both Marauder and Merc, together. Funny thing was, two of them (some 50 level trooper healer and his sentinel friend) were actually killing me in the main city (Voss-ka? or whatever is the name) without any guards coming Incoming Medical Droid camping?
5. Companions. They are nice and everything, but some of them are way too powerful (healers) that others feel redundant. Also, they are used for soloing or doing areas with one friend. anything "endgame" is done without them. PvP, HM Flashpoints, Operations, etc.
What I didnt try for different reasons
1. HM Flashpoints
2. Warzones
3. Operations
Yea, basically anything "endgame" I prefer to enjoy stories so far and wait until they get rid of the major bugs and problems, until I start with those.
