Maintenance for the week of October 7:
• PC/Mac: No maintenance – October 7
• Xbox: EU megaserver for maintenance – October 9, 2:00 UTC (October 8, 10:00PM EDT) - 16:00 UTC (12:00PM EDT)
I've used Carve (Cleave), Boundless Storm (Lightning Form), and Lightning Flood (Lightning Splash) to good effect. I would also recommend using Critical Surge and Negate Magic with this setup, since Critical Surge will keep you alive and Negate Magic will lock down entire groups of enemies all at once.
