This comes up a bit and this is my take on it. There is enough AB on the build to hit epic DQ with PA on with moderate raid buffs, -1 from max possible assassinate DC (I think) - should be decently consistent on anything that can be assassinated, no fail Holy Aura scrolls, enough HP to participate in every raid/quest in the game (main target here was 500+ for epic lob), repeating crossbow proficiency for decent ranged DPS as needed etc.
Feel free to point out any glaring mistakes, just woke up from a nap.
Happy to take suggestions on tweaking enhancements.
Happy to take suggestions on tweaking gear to improve it or for specific circumstances.
Not sure whether I should reslot +2 exceptional intelligence to allow the Alchemical weapon to be used for doublestrike purposes on Assassinates, suggestions on that welcome.
I've included some hypothetical ideas such as getting enough intimidate to tank HoX on elite, this is relevant for me as if/when I try this build out I'll probably have all the gear necessary for it anyway (my completionist character).
