Another reason to have 2 engies, is the pain control. Me and my 'Main Officer" always run together and we are both engies. We can pin down gaurdian by both throwing our pains out at different times. Takes paying attention, but its a big help. Heck, 2 Engies with Pain defeat the need for a commando on gaurdian runs. haha.

You were in a newb group who do not know how to adapt. Ill run any combonation of classes for a gaurdian run as long as there is 1 engi. Being myself. haha.
