I disagree on this. The AC to gold and Voting Token to gold is the same on purpose I believe and that should not be changed. They should be equal. One cannot be the more than the other as then a new forum post would be made saying it's not fair that AC gives less gold than voting, even if both are important.
AC is the better exchange rate one hundred percent, I agree with you there but I always saw that gold exchange being there for the lvl 80's that don't need the xp anymore nor want any of the cosmetics. The 100 gold (I think that is the exchange off the top of my head) is not meant for a player to get rich off of it, but it does build up over time. I have seen some people exchange some insane AC numbers for gold in the past.
