Would you forget mining for?

I'm only playing a hunter, I have now a decent gear (6.2 k gs)

My current proffesion are: mining and herboralism

I made lot of gold with those profession

I know this is not bis prof for hunt, should I forget those prof and get for example ingenieuring?

I mean , is it really worth to have eginior as a hunter?

I'd say so. You can craft Iceblade Arrows which add 91.5 DPS.

Engineering for pvp, haste on hands, parachute, nitro boots, everything fine.

i'm mainly pve players

but can i still make lot of gold with ingenieuring?

With engineering a lot of gold? No. Every enchant requires engineering skill and arrows/bullets are quite cheap.
Only mechano-chopper you can profit. But waste 12500 gold for 18-19k gold sell.
