Dragonhunter trait changes (ideas)
Defender’s Dogma – no change needed. It’s a way to proc more burns, which we’ll need for burn uptime now that they don’t stack in duration. Admittedly it is a weird trait, but it’s fine for its effect and position.
Piercing Light – better yet, “Traps hits inflict bleeding. When you use a Virtue, reduce Trap recharge by 3 seconds.” Active skill recharge is all the rage, and this instantly gives synergy with Radiance and Virtues, and to a lesser extent Valor.
Zealot’s Aggression – Longbow doesn’t need a -20% recharge, as it’s already been designed with the the reduction in mind (4s instead of 4.75, 10s instead of 12, 15s instead of 20 (extra second taken off)). The only thing Longbow needs is #5 reduced to kitten (60 -20% with an extra 3 from rounding to a more “flat” number). A 60s reason skill is abhorrent. There are multiple elites shorter than that, even if it is strong.
Big Game Hunter – no change needed, like you kind of realized. Plus, the 15% is only for you, while the vuln is potential party support.
The only trait that really needs work is the one the Devs already mentioned, and we don’t really have an idea on what that might be.
Had a post suggesting changes a week back
https://forum-en.gw2archive.eu/forum/professions/guardian/Thoughts-on-guardian-DH-traits-skills/first#post5083144 even has suggested changes for base guardian skills that seem underwhelming like zealot’s defense, protectors strike etc…
