Return of Reckoning

Hello,
I'm relatively new to the game and just started to level my crafting professions.
I've heard via the ingame chat that engi is good for aoe farming for butchering or gold and i wanted to ask if hes
easy to play and which masteries i should go for, maybe a short list of the most useful skills for aoe farming?

But I'm just happy if i get a proper build with tactics, weapon choice and masteries

thank you in advance!

I just spec something like this when i farm

Main thing is the healing keg, alot of aoe and good ammount of armor with tactic+buff+pot.
put down yor keg and turret and pull mobs to you with range and just aoe in place.
