Guild Wars 2

@ Kardiamond
There was at least in the BWE’s a skill called “Mine Kit” with 5 mines on a separate CD.
one was able to detonate them alone or all together with the toolbelt of the kit.
to get the boon removal and the knockback there were 2 traits, one grandmaster in inventions (boon removal) and one major in explosives (knockback)
it was actually a bit too op (controlling a dolyak route with 5 mines is op imo) so they changed it to “Throw Mine”
i loved to knock someone away from me with a hidden mine (traited to be invisible out of combat) but it srsly needed some tweaking

Only an engineer can be a support-only profession in a game without any profession being dedicated to only one role and still be called “versatile”…
