Who should I make ?

Hi, I have Ele and Warrior, my main characters. With warrior I farm destroyer cores, and green items with ele. Well greens are cheap nowadays and there is weak loot in glint challenge.
So I decided to make character, that I can farm items with rare skin, lockpicks, dyes, tomes and such.I tried E/Me lux assassin farm, but I can only aggro few at time and thats really slow. I heard the best and most flexible characters are low HP prot spiriters.
I wonder what char to make, because it's long to unlock all areas and heroes.
Rt/Mo (VWK) - I tried to do survivor on her, well failed but still 20 lvl. And it's kinda hard for me to play such char PvE, cause im new to rits.
D/Mo - Well dervs are good for their high dmg deal ability. But I dunno if he can farm HM.
M/N - Well pity that monk is weak offensively and can only heal and prot (I like to do missions and quest with heroes and henchies being offensive myself).

Ok again what I want ? - Good character to farm and to play with. I need to be sure what char. to make because unlocking major outposts and doing most missions on all campaings is kinda time consuming (20 lvl isn't problem thought)

well ele and warrior aren't limited to glints challenge or green farming
there is so much more to farm with them.
Just check out this forum. use the search funktion or the stickys.

You don't have to make a new class for farming. Eles have a few of the best and easiest farming builds.

Warriors have some good farming capabilities as well; just check the above poster's and witte was' threads.
