I have mixed feelings on snipe quest. I agree it isn't always easy to strategize around. I actually do the same as you with the Silvershield Archers a lot of the time, which is pretty strong with General Sloan. I also hate how so often when I get the quest I'll get rulesets that are no ranged and stuff like that haha.
But a good thing about the quest is it leaves you open to any splinter. A lot of people get hyper-focused on finishing the quest they just end up spamming their splinter and becoming predictable. With snipe you can use any splinter. If you have a good sniper to slot in the ruleset, you can finish up before you become predictable.
