I have 394XP to go to get to Lvl2. From my calculations I will need to do at least 2 more missions to get to end. One will be Thunderkeep to get me to Fire island which will give me 1000xp. The other is Ring of Fire which will give me another 1000xp to get to Hells precipice.
To get from lv 2 to lv 3 it requires 2000XP, that means it should be possible for me to get to the end with a lvl 2.
Dont know why I am bothering to try this, I guess I need another challenge to tie me over till the update it out.
Heres a screenshot I took at Thunderhead Keep
