Why 1/3 Gold Bid Fail
Further Argument on the 1/3 payment GDKP.

If anyone got bored by this, I am sorry
Background Readings
Gevlon’s plan on improving the GDKP
solo-rewards-for-group-effort
PUG
rule-in-gold-bid
Summary :
Gevlon try to introduce an improvement to GDKP, since GDKP do not compensate the other bidder “enough” and encourage bidding. He suggest that the final bid’s 1/3 will go to the second bidder (Instead of going to the gold pool for the raid)
The Game
I’ll try to rephrase my argument.
A given loot had been auctioned
Let Player A maximum bid be 1000g (FPBP)
Let Player B maximum bid be 900g (SPBP)
Traditional GDKP
Player A would get the loot, -900g
Player B would get nothing
Raid gets 900g
Honest Gevlon’s competition,
Player A would get the loot, -900g
Player B would get 300g,
Raid gets 600g
Zekta’s Double Bidding
Player B finds a cooperator Player C. in which, he’ll always bid just before player B (With B’s Gold).
Auction will stop when Player A withdraw.
Player A bid on 1000g,
Player C bid on 1100g,
Player B bid on 1200g, and win the auction
Results:
Player A would get nothing
Player B would get loot, -1200g
Player C get 1200*1/3=400g.
Raid gets 800g
Player C gives back the gold to Player B (He’s just a bid dummy for player B)
In Summary,
Player B would get loot, -1200+400= -800g
Player A would get nothing
Player B would get loot, -800g
Raid gets 800g
In Summary
If taking my double fire bidding plan, Player B is better off in this situation, since he would want to loot for 900g, but he now get it for 800g.
In this case, the only benefactor is Player B, at the expenses of Both Player A (Getting the Loot he value 1000g with 900g) and Raid (Getting 900g pool).
The only way to counter that is player A also use “double fire” bidding plan, but then the result is the same as Traditional GDKP (with bidding on 200g).

The fallacy of Gevlon example
At his Bid Ninja assumption, he stated
“So FG offers SGBP and not a cent more. It’s unreasonable for SG to bid more now if he did not bid 20 seconds ago, and BN has no options.”
The item valued by the FP (first player) to the First Player Break Point (FPBP), state that, the player is willing to pay until FPBP. Although it provides 0 values to the NB, He also knew P1 want the item. The Trade will occur as long as SPBP < = Price <= FPBP. But not necessarily equals to SPBP.
While destroying the item provide no benefits to BN, but this option provide an effective threat to P1. Consider the similar case in Mutual assured destruction in cold war and Cuba Crisis.
Summary
1/3 Bidding do not improve any better than Traditional GDKP, while introduce extra complexity.
The double fire loop hole had to be fixed, before it’s become useful.

You missed the reason for the improvement (as many others). I’m NOT trying to encourage bidding, nor I question that a smart guy can decrease the price paid.
I want to encourage people to be tolerant to competition. The easiest way to decrease price is to keep the possible competition out. If I’m the only spell DPS in the raid, all +hit + SP loot is mine for minimal bid. By introducing 1/3 compensation, you get gold from the item of other spell DPS, so I’m not so eager to form an all-rogue raid.
For that the decreased pot is an acceptable cost.

Thanks for the reply…
Yeah, I missed that point. For a whole raid perspective, allowing other class is great.
My thought however is that, if this double firing strategy is used by everyone in the raid (And they can benefit from it), the 1/3 thing will render useless.
Something had to be done on that, to ensure that we had the desired outcome. I would really want to know the solution of that.
Nice work on the pug BTW, will stay tuned

In most gdkp runs as is people still run up the price on items…while I may try this 1/3 method for lulz it would seem that it benefits buyers more then carriers. I mean how ridiculous would it be to see mages bidding on tank gear in an attempt to run ujp the price in hopes of being the 1/3 share winner…
