Should mod culling be based on Item level ?

I think it should.

The issue is: crafting from a white base is very strong (we all like it, and it does give value to white bases as intended) but yellow ground items end up very weak.
When picking up tier even a tier 4-5 rare, the odds of getting something even remotely workable are still ridiculously low, my best hope is for a single T1 mod for join the recombination fodder pile.

Crafting is very strong this league and will possibly be brought down a peg, but it won't fix it. And maybe it shouldn't, I like crafting in 0.3, it's actually fun, kinda tedious at times due to small size inventory and abusive clicking to filter and haul thing from tab to tab, but hey let's not kill it, it's much better than what we had before, there's actual crafting in the game now, and it's actually pretty fun.

Now how's about getting some potent mod culling based on Ilevel as we get to the topper end, to make rare drop worth considering ?
Think about it, let's say Ilvl 84 items would roll a minimum lvl 50 mods. This usually means a mod T1-T3.
That would be potentially pretty rewarding and strong, yet still pretty rare. The only way you'd ever drop a 84 Ilvl item would be to run a T16 maps (somewhat valuable and are) on an irradiated map (common, but still requires investment), be on a corrupted/purified maps with +1 level (both rare and impossible to replicate indefinitely) AND could only drop from a unique monster in the best case scenario. Seems pretty reasonable right ?
Of course you would scale it back a bii for Ilvl 83, and even more for Ilvl 82.

In my opinion this type of system would make sense. We can garentee very high tier mods on white bases with cheap currencies (and we like it), maybe let's have yellows cull out the trash tier modifiers when we're pushin into higher Ilevels, itherwise picking up yellow items is basically a waste of time.
If it makes the game too easy, make monster tougher overall or through map progression, introduce harder late game content for people to push into.
