So tired grinding t6 t8 maps..

Atm its either buy t14+maps or grind all maps until they are completed..
Thats so many maps to grind that have no challenge at all.. Outleveling the map difficulty is the number one thing every single gamer experiences.

GGG whats up with that?

By your logic where do you buy t14 maps when everyone struggle to get t8? There are multiple ways to progress with atlas, the easiest one being farming Uber lab for map treasure. You are guaranteed to drop a couple of red maps every time you hit one of those, so I don't see a problem. Otherwise if you hate lab farming, go ahead and trade for them. If you are SSF then Uber Lab is by far the best way to obtain red maps to progress.
