The voting system in Elo is pretty simple get over 1050 and you get one vote for every 50 Elo you get after that you get another vote to go toward saving or banning a card.
- Characters must receive at least 5% of the votes with a majority of negative votes to be banned. Otherwise they will remain valid for the ELO deck format.
This is a crucial statement. Above 5% AND majority negative votes. Again simple enough stuff but let be real here. Only 1 car was given more than 10% of the vote (Rex Swieg). You may ask why 10% matters, but 10% is actually IMO opinion are more important number.
If a card gets above 5% of the votes (in banning range) but below 10% and is kept that means had the people who voted to save the card not voted for that card and instead used their votes on something else then the card would have failed to be above 5% and would have remained unbanned regardless of how many people voted to save it.
When a card reaches 10% however then it is possible that voting to save is the best method of keeping the card you want in the format.
The following cards are banned this week an received between 5 and 7% of the vote.
Ruru, Arno, Wee Lee, Pilzken, Oshitsune, Yayoi Cr, striker, Lowki and Parmabarb.
Each vote this week is worth approx 0.041 of 1% in the banning
This means that if more than 47 people voted to keep Ruru they wasted their votes as this pushed her over the 5% limit and as little as 8 votes to keep Parmabarb pushed him into ban range as well.
I learned a bit from this though I generally vote to ban regardless.
I want to mention that people are more likely to vote for what at the top as it is the first thing to appear and generally are more likely to vote for what has a chance at being banned verse something that has no chance.
