Yes it has been noticed and no, there was no announcement, they just did it. Doesn't affect me and other Visa teams that much but a total nightmare for AH only teams especially with increased injuries they are reporting in Guilds. Not a good move by SN as they are still potential future customers even though they do not spend now but by doing this they are more likely to just drive them away from the game.
Not the sharpest pins in the box.
