Rushing in the realms generally have two possible reasons:
1: you want to do some quests real fast for their reward.
2: you want to get to the areas where the good experience is.
Here point two is plain and simple invalid as /players 8 negates all need for experience runs, if you play all areas on max players you'll end up as a patriarch at lvl88 or so, plus the rewards are alot better than when rushing as you'll be bound to find alot of items because of the increased drop rate.
So I guess the answer to your question is, there's no need for rushing here
