Hi!
When I reach 60 with Galek, my other 4 CB members were = FB - Juliana - Rector - Erinia.
Actually (3 months later) my team is = BEK (60) - MaShalled (60) - Ghostborn (60) - Rector (50) - FB (50), wich allow me get Hard in 1 key in auto.
Still waiting for skullcrusher to improve a better setup with Jareg :D
I began with Kael, Tayrel, Apoth, and for the last two slots, depending on affinity, Athel, Knight Errant, or Romero.
Now I use an Unkillable Team, the Slow Skullcrusher, Tower composition, made up of Roshcard the Tower, Skullcrusher (Gnarlhorn on Magic), Doompriest (Grizzled Jarl on Force), Vizier Ovelis, and Frozen Banshee (Fayne on Force).
