Can we get some real crafting options for maps ?

Im for sure not wanting to remove maps as a chaos orb sink.

But:

Why arent we able to craft certain mods on maps? At the moment there only a few mods, league specific, available and imo they are too damn expensiv for solo players. I would love to see something like these:

pay 2 (or 3 Chaos):
- randomly add rare, packsize or magic monster 20-50%
- randomly add temporal chains or fleet mod
- randomly add a curse from the following list: curse1 , 2, 3 etc.
- randomly add vulnerability or deadly
- randomly add monster gain p/f/e charges

etc.

Wouldnt this be a nice add on for maps or are they such huge balancing problem ?

massively unbalanced... everyone would just packsize, magic, and rare, and then easymode the rest for quantity.

current system depends on rolling mapdrop mods (packsize, magic, rare) acting as a currency sink.

heck, look at the price of zana's mods... and those aren't even packsize (ok, beyond might be better but that's what like 2ex?)
