I aid all Guildies and Friends (plus tavern) every day. Generally Guildies aid less than Friends, and Hoodies even less. Friends list I weed out players who do not aid regularly.
I used to aid all Hoodies too, but realized better to keep them open for Quests, Plus if one attacks me I can attack back instantly, instead of waiting until the aid drops off.
So I am aiding 130+ Friends and about 70+ Guildies in three Worlds every single day. No problem.
Being too lazy to aid everyone is just lazy. I see no excuse other than being too lazy, tired, ill, selfish, and mean-spirited LOL
Though if you work three jobs, and volunteer besides,or are in the Military... I can see a person having a hard time to find time to aid everyone every day.
(Two jobs is no excuse LOL)
