Thanks! For me the best classes for each part are: Abyss:hunter (by far), Bridge:, titan and warlock easiest to jump across can be done with hunter as well but it is a little bit harder, if you build the bridge it doesnt matter of course. Thrallway: doesnt matter. Deathsinger, can easily be done on any class, bubble with saint-14 might be nice to save you out of sticky situations, but with some practice it is fine on every class. Crota, if you dont have ghorn: warlock (by far), you can down his shield with 4 or 5 fusion grenades with the burning perk on. If you have ghorn: it doesnt really matter but i guess warlock might still be a little bit easier in case something goes wrong and you dont have heavy ammo. So basically, I would do it on whatever class you are most confortable with, thats why I did it on my hunter.
