I am so looking forward to the Steam version getting the 0.20 update, it's been out for over a week now but steam is till in 0.19. I understand though, they want it as bug-free as they can get before they release it on something as big as steam. Doing immortal bosses just seems to ve so entertaining, I really how the system works.
I'm the furthest player in my group by some distance and we thought it would be fun to see how far I could give people a boost. That will be a bit (or a lot I think) harder with the reward cap that is in place now but then again, it could have broken the game for the newer players in the group. I still hope the update is here on steam fast :)
