Strength is important for melee and carrying capacity, no fun to be hit with an enfeeblement and to drop out of stance on a monk. 13 starting is acceptable but 14 is much better (and so cheap). Overall though it is the cost to wisdom that I'm more concerned about, if you're putting level ups into dex then that means a lower wisdom which means less arrow procs on 10k stars for less DPS and less effects. 4.5 damage or 3% DPS? It's close, I'd lean in favour of the extra arrow procs for CC purposes.
The prices shot was something I read in the release notes iirc, possibly has been changed, feel free to check it out.
Crossbow is useful while leveling and makes level 1-6 with a carnifex look like a joke. Once you get 10k stars there's no reason to ever pick up a xbow again (check out the uzi threads for discourse on that topic).
Twists sound great, I haven't gotten into the ED's yet so don't know the details but if you can get haste boost elsewhere then sounds like an even more compelling reason to go artificer.
If you defer ranger levels there's no reason not to choose manyshot and then swap it out before taking 6 ranger. I'd possibly go 2 ranger, 1 artificer, 6 monk and choose manyshot at 9 to have that 2/3 to 3/4 archery feel from level 9 and then swap out manyshot before 6 ranger (which is still cheap at level 12). Moron Helm and maybe yugo pots is going to make 10k stars at level 9 nice I hope.
