Monster mode.

New player here. Can someone explain the point of this? I’ve only ever gotten to lvl 18 (warden) when i got to 10 they said something about monster mode. Sure you all know. I gave it a try. Its kinda terrible. My poor orc raider has be theoretically ass pounded but dwarves Humans and gnomes they are lvl 148 whilst i maintain 150. They are much superior to me in every single way. What is the goal? Why am i so pathetically weak? Am i to find many friends to be able to gank 1 lvl 148 mob? Is that the fun? I cant even ask for assitance or questions since i havent played very long. I think 2 hours.
