Currently leveling my champion (3rd char) after a long break in playing him and seeking some advice regarding the legacies to select for Champion rune so have a couple of questions...

1. Planning on having a single target and AOE build and wondering would I get away with just leveling a single rune that will cover both builds. I dont plan on attempting anything above T3 on him.

2. Are champions a viable option for tanking using the Martial line? I have ignored this line completly but wondering if I need to give it a closer look. Would this require a set of tank specific weapons/runes?

3. For a single target build what are the must have legacies for the rune?

4. For a AOE build what are the must have legacies for the rune?

5. For a hybrid rune what would you recommend?

Appreciate any thoughts/comments.
