[Heartily]

I sub Blue when solo 67 beast, regen and +8 chr from spells,
cocoon def and headbutt/bludgeon combo for the power for
last kill if pet dies.
I sub Red when out with NPC for cures/shell/protect, dispel and silence
are really helpful, regen and blink are useful. As red, I can cast invis/silence,
wander thru mobs ( anticans for example) and still use fight command
on pet without dropping invis/silence, run to safe area, call pet and
reattack in a safe area.
I admitt, I haven't subbed white so I can't compare either sub to that,
but red and blue suit me just fine, Beast is flexible enough to use options.
Problem without white, people keep asking me for a raise because they assume
beast subs white. I feel bad when I let them down !
