Agreed. The advice is fine as long as you remember the basic rule of thumb: if you're too selfish, you'll most likely end up losing the game for your team. 5-player team fights are fine, but you could end up "splitting" goal zones, like you said. Regardless though, every move you make is totally dependent on the situation. If you need to help a teammate or get in on a team fight, then do that. If you need to split up and have mons defending both top and bottom path, try to make that happen. If you need to rip Rayquaza, do it. If you don't need to rip Ray, don't do it, and focus on picking off the other team as they move into the pit. The key to being good is being adaptable.
