one of the biggest things thats prevented me from wanting to log in and play this game is knowing that i'll have to buff my character before i want to go and do something, or not wanting to log in and play because my buffs only have a short (less than 2 hour) time left on them. this also means when im logged in and playing i feel compelled to make the most efficient use of my time so i don't "waste" my buffs, meaning if i can't fully commit my attention to the game i dont log in at all. A permanent kind lady removes the tedium and unfulfilling "gameplay" experience of loading in dead toons to buff one character, then loading in a another set to buff your 2nd character.
the short term nature of kind lady currently has a few issues, most notably the fact that if you play at weird hours its unlikely you'll ever see her. another issue is that you currently have about a 1 hour window to get buffed by her. This means people tend to drop what they're doing, whether it be IRL, playing different games, or maybe even grouping or questing in SoD, just to get their characters buffed. Contrast this to blessed zones, which stay active for about a week at a time. Having a longer window of time to take advantage of blessed zones means you can do so according to your own schedule.
Please make kind lady permanent, nobody wants to do chores anymore just so they can play their favorite MMO.
