You have a fair chance of rare loot: you have a 1/6 chance to pull it yourself, and you get 1 raid closer to a 20th reward list. That is all you should expect, and all you are entitled to.
If you expect to demand dibbs on other peoples loot, perhaps it is
you who should post what guild you are in, and your character names.

I don't think you need to worry about grouping with someone from Thelanis. ><
And even if he was on Sarlona, solarnight and Kophie would probably be declined after being myddo'd anyway.
Edit edit:
It should also be noted that for these organised guilds, you are much more likely to get loot compared to a group of random puggers. Random puggers are generally not as well equipped and don't have as many completions (i.e. they need more loot than someone from an organised guild), and in many cases will pocket raid loot that they will not use (i.e. taking madstone boots on their wizard because it says potency on it, while being too nub to know that the random proc prevents them from casting). Whereas groups comprised of experienced guilds are much much more likely to not need the majority of loot, and will only pull the loot that they need.
