It throws class balance OUT THE WINDOW.
Bow down to the rogues, knights, and clerics people. They are better than you.
Time limits make LDoN nothing more than a DPS orgy. No class comes close to rogues in DPS. Don't even try doing a hard mission without one, unless you have some hella nice pulling.
Of course, you could just do normal missions. But those are mind numbingly boring. We pull 7 at a time without enchanters and don't break a sweat. Its nothing more than widdling down a large collective pool of mob hp. Its so fucking easy its boring as fuck.
So here I am, stuck with not one, but two classes that suck dick in this expansion. Thanks Sony.
Here is the solution:
Make missions with time limits that last confortably longer than they take to complete, with situtions that require a warrior with defensive and *burst* dps. (i.e. make casters not worthless)
