Mappers cant complete maps

two of them are rank 10 and the others are rank 9 and they can only complete 30-50% of the maps. do they all need to be rank 10 to complete the maps? right now i dont think they are even worth running. too much cost for no returns

edit- just to clarify, most of the maps stop at 30-50% completion.

If they are all lvl 10, they can complete fine alched T16 maps:


For 8 mods corrupted maps, they have 55%-100% completion rate, but rewards are still better then just alched maps.

For guardian maps they suck, they get a fragment in like half of the maps, and they die a lot more then in normal maps.

i think i'll just remove them for now so they dont use gold.they are just not worth it for me. been running them all league and the most i got was 2 divines. the rest is just junk. they are really not worth running unless they are rank 10 and its too hard/expensive to get them all to 10.
