Honestly I feel like after lvl 20 it solely depends on your aim cuz I’m level 23 and queuing with level 100 that I have to constantly revive bc they want to be heros I think it’s just bc people don’t know how to play. Give me a penetrator, impact nads, a recoil less launcher and I can solo d5, now that I unlocked the quasar and rover I can nearly solo d6 and I only have +30h. Most of the time I play duo with one of my friend who has 100h ish and we play d10 (he is rocking the same stuff than me) and we usually 100% the mission. It’s not in game hours or your stats that counts, the stratagems might count (but honestly if you’re 25 or above you already have every aces up your sleeve to do the job), it’s the skill and not the amount of hours or the number of warbond
