Expansion LevelsFollow

Hail all,

I'm currently level 26 and working on LDoN content. I own the first 10 expansion packs for the game (I'll get POR another time). What I'm curious about is at what levels can I start working on the content in the other expansion packs. I know with DoD I can jump into MM's at any time, but having done a few of them pre and post nerf I have to say I'm not a fan of them. I actually prefer the LDoN adventures much more.

Could someone break down which expansions are explorable to which level ranges?
