I just made a dwarf engineer yesterday and id like to know if anyone has a high lvl engineer and if so is it good in pvp?

not really no, good assist i guess with all the turrets.

I made one to lvl 7 and it wasn't bad at all. Only problem I found was that the turrets weren't as good as I thought and the grenades, etc have to be so damn close. But yes I would suggest it if you appreciate using guns.
