“The Road to Better World War Matchmaking” aka Sandbagging!

[Flailer]

Thanks for more details! This sounds promising!
Can you provide some clarity on #3?
"Instead of an absolute comparison, it now compares the percentage delta in power; a simple change that showed a great improvement in the system’s ability to predict WR."
So, you're saying it compares the delta in power between the highest and lowest players in the alliance? What does WR mean? World ranking?

BHG_Muet. PLEASE MANTAIN THE 40Vs40 WARS OR RESTORE 35V35 OR 45V45. THE BIGGER ALIANCES NEED IT. ALL MEMBERS IN MY ALLIANCE WANT TO WAR.

Sandbagging is a form of cheating active players can’t donate troops to one another but a base that hasn’t been active in a year can get get troops. Stop cheating of all kinds

 

[Vixen]

Two years later ..... but yay for muet .... where is the post about getting rid of the cheaters

 

[StarTrekAlliance]

Thank you! This sounds very promising! It may be cool, if feasible, to add Individual Glory based on your wins against opponents in WW with consideration to whom you attacked (how relatively tough were your opponents) and also consideration to how well your base Defends. That would be cool! This feature would be nice for alliances like ours that are very inclusive and allow all who want to War regardless of skill or age. Thanks in advance for you consideration!

Joe really likes his acronyms.
But wth, idgaf about mp or ww, I'm CWA.

LMFAO - This thread was created 2 years ago - sandbagging has been alive and well the entire time - why does it take this long to start fixing a problem that has plagued this game for so long? And if it takes this long to address sandbagging how long until cheating is addressed properly? My guess is never because it doesn’t benefit BHG/Nexon financially. All they care about is daily sales and furthering their P2W agenda.

 

[StarTrekAlliance]

Agreed! I would think an easy potential solution would be to not allow participation in WW if the player has been inactive for more than 30 days.

MM (matchmaking), Elo (skill levels calculation), WR (Warm Regards )

ETA for MM changes BHG_Muet ....Thanks.

It’s effecting their bottom line now players are leaving by the droves. They won’t admit that they screwed up this is why they sent joe in to try and stop the bleeding I think it’s all talk.Every day the game dies a little more

 

[Cannibals]

WR = win rate

Surely it must be related to either declining download numbers, declining revenue in some area, or declining participation generally. In August 2016 I wrote (in another thread) that "we should be operating under the assumption that [sandbagging] was embraced from the moment that World War was introduced here." It definitely encouraged the creation of new accounts by legacy players. More than two years on, and considering that this game has remained viable longer than many others, I imagine we are reaching a natural point where departing players are close to outpacing the incoming players. Might as well fix the matchmaking now, when almost all of the secondary/tertiary accounts used as sandbags are already created.

Yet another nexon special BHG_Muet. We got matched against 10 cwa while we only have 1. They're ranked in the top 200 while we're not in the top 1500. Their glory is also a lot higher than ours. We weren't spinning the war search for very long either. When is this ridiculous match making going to be fixed?

 

[QuébecGlory]

Matchmaking is not by rank, but points available are. Match is made by average level. You probably have a lot of middle levels like global and industrials which kill you in matchmaking. From what I understand, this standard deviation factor will be taken into account in the next matchmaking system, but unfortunarely only for the purpose of splitting available glory points.

My suggestion, learn about standard deviation, modify your ww alliance composition accordingly, and see the result. Alliances with higher SD win almost every time.

For a quick explanation of SD, it's the difference between your tops and bottom, compared to your average level. If your top player is 210 and your lowest is 170, you will probably lose. If you have 10 CWA and 10 iron age, you will probably never lose. Don't kill the messenger, I'm just explaining why you get match 1 vs 10 CWA.

 

[Cannibals]

Spot on. High SD has always been a factor in mismatchmaking.

 

[Dracula3811]

Our top guy is 257. The bottom is 74. The ave is 162.
Cwa - 1
AA - 10
GA - 4
IA - 6
GP - 1
MA - 1

Sometimes it's just the matter of luck, war size, and timing, my friends! ​​​​​​I remember I posted here a couple of months ago, when I put 10 warring members to test my theory :
War size 10, highest participant was Enlightenment Age level 100, then a couple of low Gunpowder and Medieval Age followed. Guess whom we matched with?
4 Atomic Age bases, the rest Industrial and Gunpowder.
It's not about sandbag at all It's all about mismatches (flaws in matchmaking algorithm), war size, and time!
However, when it comes to world wars, we would always hope that half of warring members are our top hitters, that way we wouldn't care too much whether the enemy lineups have bags or not.
Dracula, if 5 your Atomic guys could hit their CWAs, you would have won it Perhaps need more practices?

Might it not be a better idea to have matchmaking only count the top 2/3rds of each alliance, and have the weight of the top 1/3 count double?

I'm not good enough at maths to predict the result, but I'm certain it would be an improvement.

I remember the bad old days, when I was in an alliance where we had 15 AA players, 2 GA players and 13 iron age level 10 players (pre CWA). We won 70 straight wars. I think the current war matching algorithm is only *slightly* less flawed.
