New Ingenier is looking for great build :)
There are some good PvP builds in this thread: https://forum-en.gw2archive.eu/forum/professions/engineer/post-nerf-replacement-build-for-bomb-nade/3328285
Engineer traits got an overall slight nerf last patch but I actually feel like our build options opened up into some even better possibilities than before.
Engineer is similar to necro in that it can be a good bruiser, like you say: good damage, good survivability. It is different in that most of that survivability comes from mobility and dodging rather than 45k hp and condi flips.
