I still pug virtually every step of my TR-ing grind. I find myself much, much more patient during the first few levels, where I meet the newest players. I have stereotyped the types of players I come across in my TR travels:
The Noob. This guy is inexperienced with the game, doesn't know better. he tends to have an extremely poor amount of hitpoints and no fort. This poor guy has to rely on what he sees in the few low lvl pugs he has joined, quickly learning that "share" is a good way to find his way to the quest. I suppose the ddo wiki, ddo forums or google never crossed his mind. Most of the time, they willingly and eagerly accept advice from DDO veterans on how to better equip there toons and play better.
The Pileon. This guy has been playing the game anywhere for a few weeks to a few years. Naturally a know-it-all, they share similar traits as the Noob, only they are incapable of taking advice or criticism - after all, they understand the game well enough to be carried through everything, right? They are literally incapable of contributing to the group in any way, shape or form. They just pray there are enough veterans to finish the quest for them so they can get there 'phat lewts'.
The Gimp. Similar to the pileon, He has chosen a play style unaccepted as the norm, fully realizing it. He has probably never tried to build his characters or gear them from other players' advice, because he is afraid to be 'the same' as everyone else. They can typically be found dual wielding bastard swords with a rogue icon next to there name, with a high dexterity score and the finesse feat. He doesn't take the toughness feat or enhancements, because he 'doesnt have room' for them in his build - and doesn't realize that his ingenious plan of never having aggro just doesn't work. On the rare occasion, this player is an intellectual who purposefully goes against the norm, claiming to be an 'anti-conformist'. because going against the game mechanics makes them that much cooler.
The Veteran. a solid player, follows instructions well and works with the team. He prefers not to lead groups, and will wait for a guildy to put together a group or hit a pug LFM. They tend to be a bit more quiet when it comes to pointing out mistakes or delegating within the group. They just want to get things done.
The Elitist. This guy has been around for years, has taught his fair share of noobs how to play the game, and is tired of it. He has gone through the motion of leveling an army of toons, understands the game mechanics extremely well to know the ins and outs of all classes. He tends to not mind putting a group together to get things done for himself. He is short-tempered and has little patience for petty errors or mis-communication; after all, raids get old after you have completed them several hundred times. Newer players tend to find this guy very snobby and will squelch or avoid them at all cost, thinking they are grouchy, condescending players. And they are probably right.
The Solo-artist. Best players in the game, they understand the game mechanics to such a minute level that they are able to conquer virtually all content on there own. They tend to have several accounts and multi-box, they typically are introverted and prefer to play alone. They don't mind joining a raid group for an easy completion when given the opportunity, after all who doesn't like raid loot? When they are in groups they are extremely quiet. They tend to have toons built to be extremely effective in a group and solo.
..and a few of my favorite types, can be a sub-type of 'noobs'.
The lollygagger. He is almost completely oblivious to the fact he is grouped with other players. He enters a quest just as the group finishes, and while everyone is waiting at the door to go back in, wonders around the instance trying to find that end chest only to get killed by a stray mob or trap that wasn't disarmed. He tends to be short-tempered and obnoxiously loud over the mic about why nobody won't go back in to get his stone.
The Tool. They think they are god's gift to DDO. this person is constantly chattering, because he loves the sound of his own voice. He is constantly linking gear in chat, and is quick to mumble excuses when he dies - which is usually pretty often. Maybe he should have drank a few cure serious pots instead of linking his crappy metalline weapons in party chat.
The Drama Queen. This person is friendly and polite when they first join the group. they tend to die on the single mob you left at the beginning, and then violently accuse you of 'griefing' them, throwing a hissy fit and making a scene to try and throw off the fact that they made such an embarrassing mistake. They tend to get annoyed and voice there opinion about that cleric who is not following there heels, or why the caster isn't constantly hasting them.
there are a few more types, but that's most of what I have seen in my travels
