As you reach level 49, you may think your close to 50, but it is still very far away. around 40,000 XP stands in your way to being able to use your grandmaster gear. Then, you realize how hard the quests really are.
Right now I am on the pyromancer's tomb and I am level 49. the pyromancer's tomb is actually very easy to solo except for the very last level, a fire boss.
this is just an update on ME.
but my advice for when your level 49, quest hardcore, get as many friends to come as possible.
Even make new friends! i did but he lost connection part way throught the pyromancer's tomb.
