and additional hats for PK and BK milestones.
I'm not even going to type a novel on why this would be helpful, because it'd probably be ignored and the reasons seem glaringly obvious.
10k, 20k, 30k, 40k, 50k spar wins
100k, 200k, 300k, 400k, 500k PKs and BKs
It's 15 total hats (and spar hats can even be reused, so it's less than that). I'm pretty sure the graphics team can knock that out in a week. People would immediately idle less and start sparring, PKing, and BKing more.
Why can't you just do it? There's literally no reason you shouldn't do it and plenty of reasons why you should, so why not?
Someone before told me that admins were abusing it and giving them out (manually) which let them give them to friends. I am 100% confident that FP4 or Dusty is capable of scripting a damn NPC that you can walk up to, it checks your stats, and adds the appropriate hat to your account.
If you aren't cool with hats, give out trophies like you do with the seasonal events. Give out gralats, it doesn't matter. Incentivize it so more people do it, please.
