Ok, sorry, my fault. I haven't reached the 100s in lvl so that I forgot this line - as this line is just castable by higher lvl traders.
But if the nanoresist will be increased like it is planned (for 14.5 already - not sure), then you have a unresistable (30?, 40?, 50? min) AC while traders have a 3 min buff, which will be resisted a lot more and has to be refreshed every other enemy - not speaking of the time for casting in which we will get beaten a lot - while engis have AC already up and have their pet beating the enemy meanwhile. Keeping in mind that we need to keep our deprive/ransack line up, I think this AC line isn't really an alternative comparable to the engi AC line.
