Well that's just a matter of perception.

Option 1: Short queue, but possibility of getting a party of high levels who will leave you behind, not help you if you're leveling, or worse, vote kick you when YOU actually need the XP.

Option 2: Long queue, but possibility of getting a party of players equal level who will work together because they all need the XP or a similar goal/reward.

Man, what a tough choice. . .
