Why does dispell remove friendly buffs?

[Zechnophobe]

There are a few times you need to use Dispel rank 1 or 2. Some effects are considered unfriendly that are, and vice versa. For instance any 'domination' effect will be considered unfriendly, but the target will be considered friendly to its new orientation. So if your stack is dominated, it will be an enemy. And level 3 dispel removes GOOD things from BAD people. But the effect is considered a BAD thing on a BAD person and so is unaffected.
