I guess thats why this update is under construction. To make all go for skulls too so this game mechanics won't be left alone.
As long as skulls and whatever system Split has in mind is purely for cosmetics i think i will not change really much... if however the system should give some sort of passive bonuses that you can obtain i can already see the ...storm coming from the community side.
And i mean this less from my perspective who doesn´t care about the skull at all after i did attempt for it years back and got bored after week 4 of mindless Harv/Inter shooting. Geting a skull is basically nothing else then this single activity for week after week and considering how the ladder system always worked was rigged anyways cus 1st placed never was removed from the 1st Division where it would have made more sense to send him either back to starting Division or maybe 5th Division so that he had to climb his way up again.
Basically my stand is that i not really show any kind of form of "respect" to a player who have x of Gold skulls knowing that he could sit in 1st Division for weeks/Months/years and earn them "for free" by this mindless Score farming.
