i also seem to be regulaly abandoned by the group or left behind when fighting

well some times when i get a group that follows the rules (sort of)you lot talk about and the tank aggros all mobs then i go after the weakest or the ranged then most of the time i end up on my own so far the worst time was against 5 mobs and the rest of the group said i could deal with it and buggered off to get more nut then i do also seem to end up in a lot of groups with the 'not so rare' cowardly guardian

Sounds like these groups consisted of rather unexperienced players, which is quite common at lower levels. You just have to live with it until your level raises and you later group up with more experienced players.

I suffered alot from that too, especially since as guardian I am at highest risk. But right now, being L37, I found that things improved alot. Actually it even seems that they like it if me - being tank - asks each class to act like this or that in the team, and people react very understanding.

Summary: Your observations are pretty normal, things get better later.

Spot on Tigrim.
That is quite common behaviour in low-level groups Galatyer.
And nothing wrong with it really. You learn by doing and making mistakes. (Naturally it can be as irritating as hell when there are some people that just won´t listen and don´t want to take any adivce at all.)
But the fact that they are leaving you on your own doesn´t seem right to me.
If you can´t get them do things like you´d like to, better just do things like they like it. This way at least you don´t get the blame

In my experience people start to learn about tactics of fellowshipping from 30-35 upwards, when fellowship quests start to get a bit harder and you have to fight against more than just few normal elites at a time.

My opinnion about the attributes has changed a bit in these few past months...

Might is definately still the most important thing, but nowadays I try to focus on increasing both will and fate. Vitality is something that i´m not bothered at all at the moment.
As the questing at the moment for me is mainly(only) fellowship-based, it means that i´m usually always with a healer or tank. So either i get healed or don´t even get that much damage, so sod vitality i say!!
it´s the most lowest of my attributes by far. It´s something like 146 at the moment. You´ll see even minstrels and lore-masters with higher Vitality than I have

Like I said earlier, Agility is good to have, though not really that important. But as the gear having Might in them, usually tend to have agility too, agility is my second highest attribute at the moment.
High agility has it´s definate benefits though...crit crit crit crit, so don´t really mind it being quite high.

well Marlon you can be happy now on the screen that come up when im loading the game just after the intro film it says that champs will be getting an upgrade this time

p.s marlon when i wrote that thing before it was because i was in a bad mood from the group abandoning me in the great barrow

oh guess we have to live off our natural skills then unlike that other lot

well guys - look at it from the half full glass perspective:
The Champ was created as a perfect class and EVERY other class is being/has been/will be adjusted to it!

(with an exeption of minsterls of course. Everyone knows they need more DPS. And a God Mode)

...and when this patch will be released?
