Thanks for the tip with the Skeleton key dungeons. Would it mean I have to make a key every time and would risk dying and possibly not getting anything? The blood is also rare or am I wrong ?
Are the skeleton key dungeons meant by rogue like dungeons ? and do they give good rewards compared to other possibilities ?
Im trying to get to this [1.1.4.1] Trozan's Comet - Trozan's Skybreach, Lightning/Cold Caster Druid

I also feel like I made a terrible choice with Druid as my first character. I’m not completely sure because it seems he needs a lot of equipment to be effective and sucks ass on my gear Level i might also be doing something wrong and dont see the obvious 
edit: oh ! About crucible : do different difficult Levels drop different legenaries ? For example am i more likely to drop certain stuff on Gladiator than on the first Level ?
