Do you switch gear often?
I feel like I see it most often after making a fairly big gear swap but that could just be coincidence.
Here's my full, current list:
Mail Boots 32 60.00% 48
Mail Shirt 28 58.42% 83
Nordic Warlord Helmet 20 54.62% 91
Lordly Scale Gauntlets 19 54.06% 105
Heavy Throwing Axe 19 54.06% 84
One Handed Axe 13 50.11% 32
Plain Round Shield 13 50.11% 32
Lordly Mail Gauntlets 12 49.31% 47
Francisca 12 49.31% 48
Throwing Axe 10 47.55% 71
Nordic Champion's Sword 7 44.27% 207
Mail Chausses 6 42.93% 30
Thick Huscarl's Round Shield 6 42.93% 148
Thick Light Kuyak 6 42.93% 155
Nordic Fighter Helmet 6 42.93% 41
Nordic Huscarl's Helmet 5 41.39% 68
Heavy Round Shield 5 41.39% 97
German Greatsword 3 37.37% 381
Two Handed Axe 2 34.46% 20
Thick Scale Gauntlets 1 30.00% 159
Steel Pick 1 30.00% 235
So I do get it a lot but I can see no definite trend towards "doing something wrong" vs "doing something right" to spark the message. If you think you are "doing something right" then what might that be?
Well Bred Courser 14 50.86% 390
Heavy Lance 14 50.86% 191
Heraldic Mail with Surcoat 9 46.56% 129

Nordic Footman Helmet 9 46.56% 27
Mail Shirt 9 46.56% 107
Mail Mittens 9 46.56% 26

Great Helmet 5 41.39% 158
Wisby Gauntlets 3 37.37% 95
Knightly Heater Shield 2 34.46% 114
I also don't play nearly as much as a lot of people. I seem to get the message when I leave most of my gear the same (I usually switch some things out once in a while). That's the only rhyme or reason I can think of is the longer you use the same gear and the less variation you have, the more I seem to get the message.
When I say doing it wrong vs right, I would say doing it right (as far as I can tell) is to leave most o f your gear the same every time you spawn.
