... I do not want to go back to Wow at all and think SWTOR has great potential...
SW:ToR had great potential during the betas. what it has now is lost subscriptions.
Bioware did not understand MMOs when it made this game. It was made like a single player RPG. Once you reached the level cap, there is nothing to keep the player interested. Even the recent legacy system showed this by encouraging players to level new characters, giving rewards for leveling every class of every race of both factions.
When i canceled my sub, there was the ussual questionaire asking for feedback. After this is done, it suggests leveling alts as the solution to whatever the players problems are. I didnt unsub alone, those who unsubbed with me all recieved the same suggestion, regardless of feedback provided.
After playing a few MMOs and watching all of them slowly die, i would offer this advice to any future MMO developers: Have as much endgame content as possible BEFORE launching. Dont wait for 3/6/9 months down the track to add the endgame content as "expansions". Also, dont ignore PvP. MMOs are about PLAYERS interacting with OTHER PLAYERS. The content is the means of that interaction. One of the most popular ways players like to interact with eachother is by attacking and killing eachother. If your PvP is poor, your game is doomed.
GW2 is kinda appealing, as filler until something else comes along.
But i'm more looking forward to the Neverwinter MMO later this year that features a toolset for players to create their own content.
