I just started my alt Dark knight. I've noticed that my health goes down really fast and I really don't want to stress my healers out too much. I know poetics gear is at lvl 50 (I am at sub lvl 40 right now) but I was wondering if I can just save my poetics for the lvl 60 ones instead. What would be the cheapest/ least time consuming way to gear up decently until poetics gear?

I am just using the bits and pieces of gear I have collected leveling my main right now...
