That's only true for the first one or two spawns, and even then only if the three nodes spawn far away from each other. If two of the nodes spawn near each other, then an early clash is pretty much inevitable.
Once A's and S's start coming out, the combat really gets going. Yes, the first minute or two can be slow, but once the fights start, they're much more intense because you know that every player's actions really count. 72 man can be a bit of a cluster#$% sometimes, but 24 man really tests your skills.
