DL and relic weapon will do you just fine in Coil and if you roll Coil with the backup class you'll get to Need the Allagan that drops for it. YOu could also be more frugal with your myth purchases. If you deck yourself in ilvl90 in the main armor slots you hardly need to upgrade your accessories to Hero's. This point would be completely moot if they had gotten Crystal Tower in at launch but unfortunately they didn't.
