By optimally play all the classes, are you basically wanting to see all the class stories I guess?
Each story is different but they follow a very similar pattern. You get order hall quests unlocked at 100, 101, 102, 104, 106, 108, 110 I believe. To start, you'll do some quests, get sent all around the world, recruit your first two followers, and have them run some short missions. I think it's at lvl 104 that you reach your first time gate, where you have to run five 12+ hour missions, and you only have the people/counters to really run one at a time. When you get to that time gate, it would probably be a decent time to move onto another character.
There is a second time gate, not sure if it's 108 or 110, my characters have always been 110 before I've sat down and gone through the class campaign enough. Once again you have to run five missions, 16-24 hours this time. Another good time to switch to another character.
Please be aware of 2 things:
1) Initial scaling at 100 is tough. You'll be wearing 790ish and the mobs seem tuned for 805-810ish. You might find it preferably to gear characters up a little through world quests so that you can more easily complete the class campaigns when you are 110. There's usually 2-3 world quests rewarding gear a day, so you can slowly gear that way rather than spam running dungeons.
2) There's no way to passively gain order resources, you have to go out and do content to get them. My current leveling path, which doesn't really bother killing many rares, still ends up at 110 with 9,000 resources, which is plenty for running missions. However if you're putting in artifact research on CD, which costs 500, and doing class order hall research which costs thousands, you can run out pretty quickly. If you're just there to see class campaigns, I'd avoid order hall research...
