Why low lvl players spam stratagem hard mode?

most of the times when I join I already join into an active fight which leads me to believe that the folks here just have no clue what they're getting into and just try to run through it. that always fails miserably

when I do absolutes, I always see that people wait to see who else joins first. that's great because you can see if it's worth your time or you need to drop someone or just drop yourself and move somewhere else. but with the new mode people are just joining hard with zero prestige and level 4 and I have no clue what they're expecting to get but it just wastes my time.

strangely enough, when I go to the normal mode I see the high-ranking players but when I try go to hard mode I see all the low level folks which could be amazing players but they're just not there yet and I have no idea why this is the situation most of the times.
