Guild Wars 2

So my Engi was my first character I made and it’s been awhile since I played it but I enjoyed him a bunch and wanna get back into the swing of things, I pretty much know nothing about how to build him or combos anymore, any tips to help get into the swing of things? (Is Rifle still great even though hammer is there? I like rifles)
How is the survivability?

What game mode you want to play (PvP,PvE,WvW)? In WvW Rifle (with the proper build) can be really strong , your survivability depends on the build you use and how well you use it.

I play all three

Rifle is still a strong contender.
He’s been nerfed into the ground but still has decent sustain and defense.
Your main goal is creating fields and to some degree focusing on damage and using mitigation like shields for defense.

Engineer, due to the nerfs and a change in which conditions stack, has gotten more complicated to play though for conditions.
