How about a few buffs that improve the DQs or make them more rewarding. A buff that raises the reward and a buff that reduces the target required for completing a DQ. These buffs would be a single use buff available for gold at the AH and/or with a high stam cost. So, as an example Travel 1000 tiles. Gain +150 Allegiance Tokens, could turn into Travel 500 tiles. Gain +300 Allegiance Tokens.
I'm all for shortcuts, etc, but these DQ's aren't designed for us to gain, they're to keep us active. This is why QH doesn't work for kill x critters, why titan doubler isn't effective, why critters killed when conserve kicks in aren't counted. Even though I know the majority are thinking yeah, I want this easy button, I'm gonna play devil's advocate here and say it defeats the purpose of what's usually a 10 minute quest each day.
In summary, I'm thinking no.
