I have seen so many people post negative comments about the game saying that it has been made so easy to solo that why would anyone ever group.
I am only a lowly level 10 conjurer but unless I am playing the game completely wrong, I pick up a lot more exp in a pty than I do on my own.
When soloing, I can take down Easy prey (blue) and Decent challenge (green) but anything more cant be maintained for any length of time (though i can win a one off fight). In a group I can earn a lot more exp taking down Tough (orange) and very touch (red).
In terms of exp per hour it is MUCH higher for me when grouping (as it was for others in my group this afternoon).
The game seems to be following a similar path to FFXI where soloing can be done but is very slow - grouping is the way to go past level 10.
Is this your experience too?
