More custom-made server quests like Wrath of Forest would be cool. I'm getting tired of just playing TTF whenever someone enters my room.
What I don't want to see, though, is any pandering to the players who want to make Ultimate even harder than it already is. I mean, I understand why high-leveled players with high-end equipment would want a challenge, but for average players like me, Ultimate as it stands is already a hassle. I'm barely scraping by, even after finding some low-end rares. I haven't been here long enough to have gathered an entire warehouse full of awesome stuff. Bumping Ultimate's difficulty even higher would turn those awesome rares into a requirement to survive, not a reward for one's time and dedication.
I don't know what the answer is to giving experienced players a real challenge (theoretically it should be Crack mode, but I haven't seen that available since I joined), but whatever happens shouldn't make things even harder on the newbies.
