If me and my friends are playing duos, triples or quads we always just wait to get wooden protection and then attack team that is closest to us, then we go to the middle, if possible collect first emeralds and put obsidian on bed, and from that point, we just stack. If I play solo just get some wool, put one layer of wool protection on my bed and immediately try to disqualify the person next to me... Then I go to the middle etc etc... Not sure if either one of my strategies can be called "rushing", but so far, It works best for me and my friends.
