Very solid routine, some things I do differently is 15-25 stockades since the 100 can pull entire zone very quickly, 45-58 sunken temple just park your lower levels in the middle ring so they get kill xp and I've been able to clear that place in sub 3 mins a run. I also add mana tombs in the mid 60s since exit is very close. Also, as soon as you can do gundrak, I believe its 73 or 74, I find it to be the best xp/hr at the lvl. Take it all the way to 80, small dungeon 6-8min clear time, and exit very close.
