no you can't buy black hole gears from dailies as you put it. you buy them with weeklies. only one none-ops mission gives the commendations. and only 6 commendations a week from that source. and like you said, 10 weeks to get a single piece, that's 3 months bro. seriously, no will complete their black hole set from that weekly alone. and in 3 months the next tier will come out and you still wont be able to do story mode explosive conflict with your 1 black hole piece and absolutely no ops experience. and in a year, yes a year, you can have 4/5 black hole pieces. a year from now the level cap will probably be raised :/
so yea, not a big deal. calm down. it was meant to ease people who are doing story mode into hard mode EC. those people can buy a new piece every other week or two with weekly, story EC and nightmare KP. also, those pieces have different stats from campaign that will probably get cannibalize for mods.
it's gonna be okay. keep calm.
