No maps. I can't progress.....

I'm currently doing T7's and I ran out, now what? literally the only options is for me to spend 10s of thousands of gold on T1's to combine them to make 1 of my tier. Or I have to go all the way back to doing yellow T1's hoping I even get map drops. I have put all my atlas points into having a chance of getting maps a tier higher and am doing maps with 250% map drop rate and not getting any. I do maps that are tier 6 and 7 and get T1's. The solution is to just have doryani sell the maps based on your progression so for me he would sell T1's - T7's. Please make a change to this, I can't progress at all. I shouldn't have to buy maps from the marketplace.
