Guild Wars 2

You can get (successful) attack verse defense numbers from the WvW achievements.

Yaks: 3545 /1838 (1.9:1)
Camps: 3262 / 205 (15.9:1)
Towers: 2040 / 801 (2.5:1)
Keeps: 646 / 590 (1.1:1)
Stonemist: 77 / 183 (0.4:1)

What sort of ratios do you guys have? Extrapolating from my numbers, about half of keep attacks fail, and more than half of attacks on SM (although there will be some bias from getting more than one defense tick for a prolonged attack).

Yaks: 1239 / 591 (2.1:1)
Camps: 1,088 / 97 (11.22:1)
Towers: 459 / 109 (4.2:1)
Keeps: 200 / 165 (1.2:1)
Stonemist: 24 / 18(1.33:1)

Those are my ratios for 394 hours of game time.

Yaks: 7382 / 3110 (2.37:1)
Camps: 5387 / 661 (8.15:1)
Towers: 2516 / 1005 (2.5:1)
Keeps: 679 / 893 (0.76:1)
Stonemist: 74 / 243 (0.3:1)

5125 hours of game time.

Yaks: 816 / 713
Camps: 1941 / 174
Towers: 1221 / 351
Keeps: 603 / 604
SMC: 97 / 90

If you sit in garrison scouting for an hour and a thief every 3 minutes taps the gate, you will have 20 successful keep defenses during that hour even though there was no assault on the keep.

Crius.5487:

If you sit in garrison scouting for an hour and a thief every 3 minutes taps the gate, you will have 20 successful keep defenses during that hour even though there was no assault on the keep.

Only if you kill the said thief. You don’t get a successful defense event by standing on a keep doing nothing.
