I've been playing TOR since before 2.0, and one of the things i enjoyed the most was the leveling combined with story. I liked how it was a reasonable challenge to level solo when relying on companions, and how Heroics actually required groups and coordination.
I was working on another toon when 4.0 was released, and since then I feel the leveling process has become much, much too easy. Since Heroics are now soloable even without using CC, and the general mobs die in one or two hits, its just no fun anymore. I think the level-sync is a great idea, but making the mobs and content even easier is making leveling boring. The combination of easy mobs and higher EXP gains means you will probably hit Lv60 before finishing Hoth or Belsavis.
I know some people are very story-focused and I can appreciate that, but for those of us who enjoy the story and leveling equally, do you feel that leveling is now is too easy?
Edit: Additional: I'm also not sure I like the 2-man FP option either. Surely there should be an option to play the FP in their original state for those who want too?
And I know the companions are currently extremely overpowered, but that's been addressed in a dozen other topics aswell. I think they need significantly toning down, aswell as the mobs being beefed up.
