While I can't agreee with your statements about loot being handed out to easy, because that was what SE intended and that's how the system is built, I agree with you regarding player "skill".
I have no problem if a player runs dungeons multiple times to get mythology gear, I don't have a problem if players join Coil runs and get gear nobody else needs.
But if someone is running around with a relic weapon, I expect that player to know how Titan HM works.
If someone is equipped with Coil gear, I expect them to know the Turn where this item drops.
And if it clearly says "experienced players, know how to dodge, farming party" in party finder, I expect the people who join to know what they do.
But let me give you a few examples of things which happened instead:
A "experienced" tank with relic, CT and some myth gear which kept spaming Rage of Halone at Ultima HM. No combo for the debuff, not once, and hate was an issue.
A healer on his 5th relic who kept dying from bombs at Titan HM.
Another healer with both Ultima healing accessories who kept dying from Eruptions at Ultima HM.
DDs with ilvl75+ who only deal half the damage of another ilvl70 DD of the same class.
DDs on their 2-5th relic who fail to evade bombs and plumes at Titan HM.
A tank who didn't provoke Ultima for tank swap and never used one of his cooldowns. But hey, he had some Coil gear.
That's just frustrating.
I try to do my job as good as I can no matter which class I play.
But no matter how much I struggle to win the fight with my team, the obvious lack of knowledge, determination or skill of some party members ruins the runs for the rest of the team.
And this makes party finder pretty much useless for the higher level stuff, because most players who think they are great because they have this or that, are not even half as good as they think.
But, hey, it's always funny to see someone searching people with average ilvl85 for Titan HM.
LOL!

Nice read ^^
