For your Rogue sniper I'd recommend an elf Assassin 4/Battlemaster 6 with archery fighting style and Alert, Sharpshooter and elven accuracy feats. Basically, 2 attacks with double advantage (3d20), only -3 rolls to deal +10 damage, and spending your superiority dice with a longbow and assassinate will deal 4d8 per attack plus 4d6 sneak attack.
So a total of 8d8 + 4d6 + 30 (20 DEX) = 80 damage
The way short rests will work, means doing this at the start of every encounter. This one will probably be my MC.
Edit: I forgot action surge.
You can take another action and attack two more times, which brings damage to 16d8 + 4d6 + 60 = 146
I've detailed the build in another thread.
