Party Size

I heard after reading several of the threads, people switching from 5/6 people to 4 for ARR. I spent most of this morning at work ... working of course; looking for the details on party sizes and bonuses/negatives. Does anyone know specifically what the ideal size to box on this would be. I was initially going to do 2, then from MiRai's videos i had a thought to use 4. But i am hearing the difficulty may scale up to 8?

Here's what I understand...

Normal instances while leveling are a max of 4 characters which is considered a 'light' party and will require the correct roles to use the dungeon tool thing (I don't know if you can actually go into a dungeon w/o the in-game tool). End-game stuff is going to need a full party of 8 or a raid of 24 (3 parties of 8).

Unless it has been changed you do not need to be specific roles to use the dungeon finder. If you are solo and que for a dungeon then yes you will wait till you get the correct roles. But if you have a party of 4 already it doesnt matter what the roles are. You can 4 box Conjurors or whatever you want. Whether the content can be finished without certain roles or not remains to be seen lol. Though i know of friends that went in 3 DD and a healer and were able to enter and finish one of the first dungeons.

Unless they changed it that is...

If you form a full party with people on your server, you can queue up with any setup you want. If you queue up without a full party, you have to use their recommended class setup (1 tank, 2 dps, and 1 healer).
