Can help, but even then a normal killstreak kit is often cheaper to buy. And people barely notice any specialized to begin with. People dont get 5 kills too often.Here's my idea: Turn map stamps into killstreak kits. Stamped weapons act as basic killstreak weapons on most maps and specialized/professional killstreak weapons with otherwise-unattainable effects on the matching map. Weapons can have multiple stamps applied (to a point), and applying more of the same stamp increases the "stamps applied" counter and does...something (maybe turn it from specialized to professional, or increase the effect's power). Selling a stamped weapon through Steam Market gives a cut to the mapmaker.
And this is totaly useless. People dont look at that window, they wont even care at all. So it still wont reward them for anything if they buy a stamp. Not only that, but on some weapons people wont even notice it. And when it can be a waste of money without any reward then its counter productive.Sophisticated Killstreak Wrench

Whatever stamp is most common would have its filter prefix displayed.
The list idea is good, but in that case... why not show it at all times on the killscreen and keep the old info? A special notification similar to the domination/nemesis icon which shows the total stamps on all maps (and explicitely also show the active map when its on) would be far more effective and better noticed.
The all map number might become common (unless its a high number), but its map specific one still will be noticed better.
The effect should be clearly visible on the map you supported. This effect should be permanent and maybe condinionaly boosted (the specialized kit part of you at least does this).
But globaly you get a problem if the effect is too strong. Killstreak kits only have 1 good noticed effect and that is the 5 kill moment and the number in the killfeed. They arent such a good idea for map stamps on its own.
So globaly you should have a unique effect to begin with, and it should be possible to boost it based on the total map stamp count.
I still keep to the part that the map stamp trail (which you now get after taunting) could have more potential.
And last... whenever i join a game the only window i did see is duel wins this season (which rarely changes). Why not show a random map and display the number of stamps for that map? And in that random pool also have the total for all maps? Showing it there could still work.
