Unpopular opinion: M3(even m2, situational) is WAY harder than hive.
hear me out.
Hive vs M3(/M2 with randoms).
Hive - Once you really know the mechanics, you have even DECENT gear, thats it. you join/form a decent group(in minutes) and you run through that shit. you died? its ok. 9,8,7 more people are there to still finsih the job. somehow still team wiped? its ok, just have a go at it again. no penalties.
M3?first of all not many people go for mutated anyway, so that filters our a decent amount of players. then, many people dont have the right protection(amulet. gems). then, you have no real way to tell which of the randoms you invite know their stuff about M3s. Then, even IF everything is good, any 'innocent' mistakes could be actually costly for your end score, unlike in hive. you could be perfect(which is already not common with randoms) for 90% of the expedition, then BOOM, one bad stretch at the end, you went from gold to silver or bronze. and the worst part is, all of this is possible even at M2, specially since for M2 most people que with matchmaking and then you have 0 control over who you go into the expedition with. I once got put into a ongoing expedition, it was M1(!!!) and that team was -20k points. i was in shock.
PS - we still want rewards for completing hive more than one time a week :)
