In Beta I used nukes that snared to keep creates at range as much as possible. When the got close I would hit them with a stun and run, set and try to re snare. If they were low enough life I would simply use my short range heavy hitting fast cast nuke chained together til they dropped. I could usually do that before they greatly reduced my life.
Grouping is were its at though in this game. You have the right idea. Go at your own pace and your life doesn't depend on a silly game. Stay away from stress boys that play that way. They will make you miserable.
You've seen all my screens in this thread, want to see some bullsh#t? A crafting room in Khal with around 16players and bunch of NPCs, highest quality and 16xAF:
That's 1024x in a window
There were a lot of players outside too nearby. FPS is the same @ 1680x as well for whatever the reason. It did rise to a whole 20 after I stopped. That shot was upon first entering. The shot's about a week old.
