This goes for ALL classes. AoE's are bad news. Players that like to sit in one spot during fights will have a tough time in some dungeons and possibly advance quests. I know its not comfortable and requires more work to move around in fights, some fights require that you do. I understand connection issues can sometime come into effect, but your hand-to-eye coordination are always in effect. You don't need lightning fast reaction time, but you do need to react.
If you're unfamiliar with the strafe feature, please take time to find out how to get your character to strafe. When you are out soloing, practice moving around in fights until they become 2nd nature; dungeon fights and dodging AoEs will become much easier.
