Very solid for clvl 14. What difficulty? Did I miss that?
On Hard or Very Hard, however, you may soon find progress frustratingly slow, with a lot of...well...death, as the deadliness of the Main Quest Line dungeon (MQL) will begin to outrun your character power progress. You may want to take a breather from MQL progress and pump your character's level with some side map-quests or Hatch quests.
Be careful, though. Side quests are fairly short (generally 2 levels with the second level being fairly small), but the monster level is almost always set at one level below your character's current level. At that relative strength, there are always a few critters that can one-shot you if given half a chance. If you go into map dungeons that show a level range comparable to your current clvl, the general mlvl could even be 2-4 levels ABOVE your character. Very deadly - leave those without completing, if you can.
Tu'Tuara Caverns are, as I recall, either 3 or 4 levels of the same theme, with a pretty nasty SuperBoss at the very end of the last level. Relatively much worse than the Overseer, or anyone in the Estherian complex. Plus, it is easy to get confused in the Tu'Tuara Caverns and swing back from a dead end, through an area you thought was all cleared out and walk into an ambush. In Tu'Tuara land, always be a lttle cautious, and keep yourself very aware of your retreat path to a cleared "island".
