I strongly suggest you amend the guide to include the PvP talents Prickling Thorns and Deep Roots, they make entangling root do an absurd amount of dmg while leveling. You can basically root a mob, move to the next, and that mob will die in seconds. I tested most of the combinations of PvP talents and nothing beats this one. It also makes soloing elites insanely easy and fast.
Edit : I forgot to add, you HAVE take mass entanglement if you go that route. You can pull 10+ mobs and instantly root them + starfall, your aoe is just ridiculous.
