I'm personally leveling all of my alts DoH classes to 50 so I'll be able to use 6/8. I started this Sunday with 100 leves, all lvl , and 5 days later I have 1 50, 1 45, 1 37, the rest are 16-17. I'd advise doing this if you have an alt or make an alt just for this if you want to be able to craft the majority of the stuff yourself. I know it's a pretty harsh grind and can be expensive. However, being a master of 6 crafts will make you a shit ton of money of launch and if you win or get close to winning in the crafter rat race your investment will pay off greatly. Total I have invested ~10 mil in making the leve items and crafting basic mats to level, plus making all the high end crafted gear penta melded for it. I can't see it costing another 5 mil if that to get the rest to 50. The expensive part the gear itself and the melds.
