This issue is terrible on so many levels

The other day i was booted from game while in a dungeon. Thats fine, i can deal with not being able to finish the dungeon but after 15 minutes of "your character is already logged in crap" i get back in. Turns out im still in the dungeon but not in a party, i leave dungeon and now i have to sit through the 15 minute wait penalty (which is more like 25-30 real time, not sure how that counter works). But why do i have a penalty when i got booted from the game? They really need to adjust the parameters for that 15 minute penalty. I am all for it for guys who come in and drop party, but for a disconnect i should be able to rejoin my party at the very least.. Very annoying issue
