Ok so, at 345 light and if you have milestones, and raids still to do. How do you tackle this?
Do I keep running strikes at 345. Turn in milestones or do raids first. What light level gear do normal and then heroic give?
Do Normal Raid
Then Prestige Version
Then Raid Lair
Hold onto Milestones till Monday Night or Tuesday morning depending on when reset happens for you
Pop them as last rewards before next week starts
This way Raid keeps pushing you up LL wise, then roll your Milestone powerful gear to cover anything from raids you didn't finish
Do it for all 3 classes like this
Save the milestones for last, unless you can run the new raid by Sunday by doing swap gear and pushing at least 1 class to it
