Shield Of Fire

[Deathrydar]

I just received my Shield of Fire spell, which is supposed to only be on me for 8 ticks at level 8. When I cast it on myself, the timer starts at 48 seconds....

However...

If I zone with the damage shield on me, the timer resets to 5 minutes.

Same thing with the druid ds when I cast it on myself at lvl 15 little over a min. But if I zone it changes to a little over 5 mins. I want the 5mins full time :) please?????
