Time limit on warzone firefight

So far the games I have played have been too challenging…not the enemies but the time we have to kill them…the first 3 rounds are easy…but the last two are hard…I think the time should increase as the rounds get harder. What do you guys think?

Literally on the last round I kill the first set of bosses and then for the mythic there is only 1 minute left…it is stupid
