This one
Or full Condi with P/S
In my opinion it can be different from map to map. On Skyhammer or on Spirit a celestial rifle build works really well . In spirit for me rifle is a must for blocking or throw away people. After playing quite all the 2 or 3 kits builds for a long time i find now in other maps that old HGH build with P/P can be really effective. It is underated but it has a lot of good things ( for example you can remove 12 condi a minute , 5 second stealth a minute, 5 second stability every 30 seconds and so on) . Damage increase with might .. and it is really really easy to play .
i don’t say that hgh builds are the best, but it is only to suggest something that for me works quite well and it is a little bit different from usual xkit builds
