Hang in there. I have a level 22 Peacebringer, and am working on a Warshade too. Shifting forms based on your situation does help fill holes in groups, as you rapidly become a "Jack/jane of all trades", being a great blaster in Nova form, and Dwarf lets you tank nicely at level 20. I have had players comment on how I constantly seem to adapt to the battle, and fill in gaps as needed. Play it, and experiment... You'll be glad you did.
