The problem with dumbing down content is that it will make lazy people even lazier.
The problem with PUGs is not "I'm skilled and they aren't"… no, they are lazy and wanna be dragged to the next raid.

You can already see it in things like AK boss. That fight is so dumbed down due to the equip out there that people don't even try anymore to avoid the room wide AOE. And that is what would happen with an easier T5. People would eat divebombs like gummy bears; if conflagration didn't kill the party member but just bring it down to 5% of his HP, the rest of the party would just hit Twintania like a sand bag, the healer would just heal the guy when conflagration is gone.

Making the fights easier wouldn't allow people to practice more or get more skills, but would allow even more people to scrap their asses watching TV while the rest of party would have to drag them to the win.

If you have the skill, make a party finder, maybe a learning one, and keep in touch with people you consider as much skilled as you are so that you can start the next party finder with more people until you find a good group to win it.

If you don't wanna communicate, socialize, work(play; just to avoid "this isn't a job!!!") toward an objective… well… why are you here?
