While I agree MH is quite boring solo, playing with more than 2 people in P3rd was the lamest sh*t since... well nothing is quite as lame as killing endgame monsters in 3-4 minutes. I am hopeful that Ultimate's G rank will pose more of a challenge through monster damage outputs but going from people's streams I've watched, the monsters seem to hit very lightly for G rank. Looks like Low Rank armor and 2-3 people will be the way to go in Ultimate.
Yes i will agree more than 2 people on 3rd was very overkill but in tri they seem to jack up the health of the monsters so it would take atleast 10 minutes for the average group of 4 to kill tougher monsters. Hopefully they did the same thing with this one.
