Who said that pls? Yes the vetos are combinded with the amount of map self, but who said or where can you see it, that if 1 less map, 1 veto goes away as well? I will self ask about this again, let's see if I can find some special numbers.
I looked for it but sadly I can't find this particular thread but I remember somebody trustworthy saying last time the map removal topic was on that we can only remove one map becouse otherwise we get less vetoes and then relic confirming that the formula is set in stone.
As for the current removal I would really appreciate if we could keep all the 1v1 maps in. I guess it might be fine to remove winter/summer duplicates, but other than that it is just madness considering how little good maps came out of map competitions we had.
I also feel that many players veto and vote on the maps that don't fit their current meta strategy which can badly affect both poll results and veto counts that are being kept by relic.
