My main issue with your zealot right now is crit and reload speed talents.
I don’t think you need to waste those 3 points to get that reload speed. flamer have good blessing to help with that and since you are using FoTF, you can utilize it to reload safely. Sprint cost reduction can be gained from curios.
As for crits, you either commit or don’t. No half measures waltah.
If you go for “scourge” you should commit. By taking “enduring faith” and “invocation of death”.
Then, you either want to take “Blazing Piety” keystone or “shred” blessing.
Also consider using “Thy Wrath be Swift”. For me it is must pick, it just makes game feel better and smoother. It will prevent occasional interruptions, while you burning crowds, which is very helpful as well.
Assuming 1.3 for Vet is the updated one I’d recommend dropping the 10% rending node which really does basically nothing for your weapon set, and pick up the Demolition Team node to really fully commit to the grenadier build.
That, or the stamina delay node. Those are underrated.
So! Took this for a spin and it seemed to do well enough, but I’m sure it can be optimized further! The only thing I’ve got changed on the weapons is Surgical on the gun, everything else is free to use.
