Tier 1 dust is quite invaluable

Ancient_One

Can kabam make atleast tier 1 dust a sellable item as 5 stars become not as important as they were.
Or
We can use 200 tier 2 dust to ascend a 6 star or say 400-500 tier 1 dust to ascend a 6 star.

Tier-1 dust is actually for ascending 4* for Arena, dust on 5* is trap

Because 5* are obsolete now, no unique use, at least with 4* you still need them for Arena.

Exactly what PT said. Use them on 4* and grind the lower arena for more points

Throw some dust on a 5* stark spidey if you think you'll ever try the Carina's Challenge. Otherwise, just forget about it or use it on 4*s like mentioned. Do you honestly think, even if Kabam let you sell them, that they would hold any significant gold value?

there are other 4 and 5 star challanges (e.g. labrynth of legends ones) that can use the dust), but in general... I agree, no real point to anyone in later parts of the game...

that being said, its also a lot rarer to get than tier 2 dust for enggame players, so it isn't like its constantly in overflow either.

^^^ we’ve had a few going back and completing older Carina’s challenges; not worth it for rewards, but a few are determined to check them off their lists.
and failing that, Arena grind.

Tier one Dust is actually for Ascending whatever you like with, because... this is a game, and the point is to have fun?

Plus sometimes the absolute best option for a challenge (like SOS, where champ restrictions can be incredibly restrictive through #Tags) is someone you don't have as a 6/*7*.

Remember the #Kree objective in Summer of Pain?

An Ascended 5* 5/65 won't really be BGs material, but they can punch up well enough to complete almost any non-PVP content in the game.
