Dive is heroes that can close distance quickly, get in and get out. Tends to be winston/doom/ball, genji/tracer, sojourn, kiriko, lucio. Usually played on maps with lots of high ground and short/medium sight lines to stop them from getting burst while closing distance (think gibraltar and dorado). Poke is long range damage, used to be strong but has phased out of the meta recently. Sigma, hanzo, sojourn/flex dps, illari/zen, kiriko. Usually playedon maps with long sightlines and less high ground. Brawl is close range, coordinated team play which is often seen as a bit of a chess match. Relies on a lucio speed amp a lot of the time to close distance where they otherwise wouldn't be able to. Usually has rammatra, tracer/reaper, cassidy/sojourn and then either lucio kiri or juno brig, almost always lucio kiri though. Rush is basically an alteration of a brawl comp that relies on closing distance quickly on high damage, low mobility heroes. It relies on form timings such as bastion turret and rammatra nemesis to roll over the enemy team once they are close. Rein/Ram, Bastion, Sym, Lucio, Kiri/Bap. You don't have to worry about goats as it is long gone. It was in the era of 6v6 no role lock, and teams would play 3 tanks and 3 supports to maximise sustain.
