-Shadow Knights are typically better at soloing because of thier DPS and ability to life tap for health. They also ahve the ability to FD if needed.
-Shadow Knight can not dual weild. This is an ability that all scouts and warrior based classes can use. (Assassin, Ranger, Brigand, Swashbuckler, Dirge, Troubador, Berzerker, & Guardian) They get the ability at level one, its automatically given. All of you character abilities are given to you at lower levels. You get a basic version and ahve the ability to upgrade as needed. At level 50 youll need to start buying your abilities.
- Furys have the higher DPS of any priests class. They can solo pretty good, but not as good as a pet class. If you plan on soloing most of your live, I would stick to something that can root and nuke, or have a pet.
