Losing Auras, traps, when entering new zone

Why is this?

This has got to be one of the biggest issues for me besides the bugs (enemies that are in corners or walls cannot be hit).

If I have 3 Fire Traps and 3 conversion traps with purity & discipline on, why do I have to lose these when entering a new zone? If I enter a new zone with low mana, I don't enter full.

So please, if our mana supply is to remain constant, meaning it doesn't go to full when entering a new zone, than can we please keep our current abilities.

It's got to be one way or the other.
