I do not understand how Althea (16 FvS) and Albus (20 FvS) get so little love. They are the only ones I ever use, and they do their job. Every hireling that uses Mass Heal (including Albus) necessarily has a critical weakness because they do not understand the concept of Quicken, but he is still far, far superior to Wyoh's 200 some odd HP.
To be honest I do not understand the concept of bringing a divine hireling for offense (Blade Barrier, Destruction, et al). What characters are you (general) running that struggle with both offense and self-healing?
