Exactly my stats.
War bows are also good. But I think a cipher will work nicely with every ranged weapon (even on PotD) because there are some really good uniques in every weapon group. Wendgär for example is a really nice superb crossbow. Then there is Persistence, a nice hunting bow that you can get very early at lvl 4 of the Endless Paths. Later you can change that to Lenas Er, a superb rending hunting bow. Combine the faster (but weaker) weapons with Vulnarable Shot. Pistols are also very nice. So basically you can't go terribly wrong if you just pick the coolest looking. ) I like arbalests because of the nice range and the huge damage - and they are not superslow. I use Aedrin's Wrecker and Lead Spitter on PotD and have no problems with focus generation. Most of the time it stays around 50 while I shoot and cast. Most fights are over after 10-15 seconds anyway...
Keep in mind that you can also use very slow guns like arquebuses or blunderbusses effectively together with the Quick Switch talent. You can fire, switch, fire, switch and so on. That burst generates a tremendous amount of focus and damage at the beginning of the fight. Best used together with Island Amaua (third weapon set) and the talent Arms Bearer. Then you get four weapon slots which you can switch untill you have to reload. That's quite devastating and works with every class.
