What kind of gear do you have? Gear plays a very big role, and the starred ARR recipes and low-level HW gear are not supposed to be doable unless you are wearing good ARR gear, or basic HW gear.
The Artisan gear you can buy from your Grand Company is an easy way of obtaining good level 50 gear nowadays. If that isn't good enough just level up to level 52/53 so you can use the crafted HW gear and tools.

Back when the level cap was 50 you had to jump through a number of hoops to get good DoH gear, but thankfully it is far easier today.
