^ I thought that the ending was also great, but my biggest problem with the game was the amount of customization of character equipment, sometimes it felt too much of a drag and that it drained loads of time. Another problem for me was the collectables and spawning unique monsters, it took a great deal of time too.
The Battle system for me was great, I did not see many problems with it, except for Sharlas AI that never healed me, herself or the other member intime.
To answer the "you walk too slow" complaint, there is a gem called Quick Step or Good Footing that makes you run faster (I do not remember which one of these two gems boosts running).
