What the fuck does a strategist even do
From the name I'd expect them to have a large range, so they can see what's going on and strategise, be able to summon or set up point on the map where something happens, maybe buffs or debuffs
But this 5* just seems to be a basic vanguard.
2 range, no skill range extension, nothing else shown, and the skill looked like just a basic self buff.
