PLDs can keep hate in several ways. If they don't want to rest but save up TP for Spirits Within.. well, ok. They still need to rely on some MP for the one or two fights in between where they won't have 300% TP to use. Refusing to rest, spending ALOT of MP + requiring Haste from RDM or PLD to build 300% TP though... that's a sign of a bad PLD. before level 56-57 or whenever PLDs gets Spirits Within - in my opinion they should always rest when possible, since a regular WS doesn't really make out that much hate, compared to two ticks with dark staff = Flash + Cure III (If refreshed at least).
I like Elfgod. I don't know him that well, but in my opinion he's always polite when I talk to him. Last night I went to help my friend out with Beadeaux (spelling lol) coffer and Elfgod stayed until party disbanded even if he got the first coffer key and found a chest just one minute after getting the key. Even if we were enough people to go on without any real problems, although... links were pretty nasty to deal with and we had one 1/3rd-wipeout of our 10-11 people alliance.
As for Sultan, as Unctgtg mentioned as a leech. I guided him through RNG flag quest and gave him some advice on cooking synths - and after that I've kinda used him as a mule sending me tortillas and other cheap cooking ingredients and he's never complained. Rather, he's pressed the fact that he'd love to do more for me - and if he didn't get it right the first time (e.g. bought two stacks instead of three) he insists on warping back and buy the last stack and send it to me. I see that as a trustworthy, loyal and humble player that really cares for my well-being. The way he expressed how much he appreciated my help even though I never did much for him other than giving him occasional advice - makes me believe that Sultan deserves help -even though he forgot to say "thanks a bunch, guys" in this particular incident.
I don't think he meant to be a jerk about that AF3. Maybe he was very happy and got so excited that he just warped out and started /tell'ing people that he finally got it. Sounds weird, yes, but when you finally get what you want it's hard to foresee if you react in a way that's charming or nauseating. I doubt that Sultan TRIED to be an ***, even though - if Unctgtg is right - he didn't make himself look very good in that situation.
