Exp Scaling in maps.

Hello to all players.

1.Want to ask what is the exp progress in map lvl ?
2.What is bonus for each players joining to the game.
3.There are stronger new mods for wand or "Tyrannical and Emperors are still the best mods now?
4.Destruction and Incision are the same as before also?

Last question in "The Awakening " there was new wand but if there is no eternal orbs so the foe bite will be still the best wand until eternal orbs back?
