Off just ONE back at16:58 this dude: -Takes blue topside Jg -Sneaks drake and scuttle solo -tps top and blocks enemies taking baron, and steals enemy's blue -leads to nearly solo killing 4 of the enemies -continues bot and dives behind t3 turret without minions -Proceeds to kill adc and support in a 3v1 then -Holds off 3v1 behind enemy lines while his team take baron and holds them off until his team arrives with minions Insane pressure holy shit. That's all in 3 mins and he backs with almost 3k gold
if i would guess, locked camera is better for barrel placement when close to opponent because he already knows the range of his barrels or something like that. when sidelaning or trying to get a ghost barrel, he uses unlocked camera for further vision, and after popping the barrel he immediately goes back to locked camera
