If DP is that big an issue for you, Anet have given you numerious ways around it in the form of
"consumables" which remove DP to one degree or another and do countless other nice things to make your life easier!

If you have GWEN, you can play the snowman dungeon and get ample supply of free candy canes every time
for free. You can save up a good dozen or more just playing that for a few hours.
Their not even that expensive to buy at around 50g-100g each, which means you can buy close to 10 for 1k from another player.
There really is no excuse to get annoyed at DP when we have LOTS of items which now remove it, add health or protect against critical hits etc etc etc. There really isnt alot more to be said about this thread and its suggestion!
