To all berserker guardians (dungeons, fotm)
How many boons does a berserker guardian provide?
They provide the right boons for the occasion not random ones. You just need to put on the right utility skills like stand your ground if cc is a problem, retreat if aegis is OP for a boss fight like fractal bosses, etc. The zerk hammer build gives perma prot while doing a lot of dps for things like high fractal and pugging.
How much support?
The zerk builds have blind spam, vuln stacking, and master of consecrations. If you bring the proper utilities along then you have all the support needed. Again, hammer perma prot is OP support if you choose that build.
What damage numbers do you get?
This isn’t typical but it will show you the potential of a DPS Guardian

And perhaps most importantly, is there a hybrid build out there to provide support/tank/damage?
Making a hybrid makes you miss out on a lot and not be worth it. The 10/25/0/0/25 gs + sword/focus and 15/15/0/20/10 hammer core builds give you all the support needed and give you a lot of dps. If you want to be tankier then use the hammer build or just run knights armor with zerk everything else if you are struggling at first since it would be better than running zerk with hybrid builds.
