Engineer

The vast majority of Engineers in PvP are playing power-based specs focusing on burst damage with minimal sustain. They have plenty of unique buffs from traits and signets that could help us identify what we're up against.

build	Specs	Notes
Power	Engineer/all	check their buff bar for Explosive Entrance, this means they are running Explosives. Usually a sign of a squishy but high damage power build.
	Scrapper	if they have Explosive Entrance expect a low sustain high damage build with Grenade Kit and/or heavy point-blank AoE from gyros.
	Holosmith:	expect Holosmiths to run high damage, low sustain builds. Their bunker builds are dead and condi was always niche. They'll roam the map and attempt to +1 fights, but better ones could also take some 1v1s. They're generally weak to conditions, but the Tools variant fares better against them. You can spot a Tools holo from their frequent but short duration Vigor procs or Kinetic Battery charges.
	Mechanist:	once again, keep an eye out for Explosive Entrance. Low sustain, high mobility, moderate ranged damage. There aren't a lot of Rifle Mechanists in ranked these days however.
Condition	Mechanist:	check their buffs for Superconducting Signet. These are midrange jack-of-all-trades, master of none specs. Can perform a variety of roles, their damage depends a lot on their Mech and the Superconducting Signet. Low sustain, high mobility, decent damage in medium range to close range. Check out this build for more details.
Bunker	Scrapper	if the Explosive Entrance buff is missing there's a chance that they are playing a bunker build. Be careful in melee especially when contesting a point as they're still able to do high damage by overlapping various AoE skills such as Acid Bomb and Thunderclap.
	Mechanist:	if none of the above mentioned signs are present, assume it's a bunker build. Low damage, medium sustain, sits on node and either stalls or tries to win over time. Destroying their Mech reduces their sustain and takes away their killpotential.
