well considering that warlocks are powerful. all power comes at a price minus natural magic because its natural. warlock magic takes away from the soul and you need to have the will it also must be that all warlock powers are bariganed for, minus daemons of course because they are the contractors. Also all Shamans ask nature for abilities, their are 5 spirits. Water, Earth, Wind, Fire and Wild, unlike warlocks who do not ask for it, they have the power to do it, but it matters on their will power and their mind in order for it to be powerful enough.
