Writ of Persistence isn't in Zeal...

...But in the Honor traitline. Why? Every other trait related to symbols is in Zeal, except the strongest one (which happens to be a weak traitline). It forces us to either discard Virtues or Valor to get the whole package or to use half of the potential of a symbol based build. Makes little sense, breaks synergies and wastes potential.

So, way back before the Specializations existed, the Honor line had Writ of Exaltation (larger symbols), Writ of Persistence (longer lasting symbols) and Writ of the Merciful (symbol pulses heal) in the Honor line to help Staff and Mace work better at their support jobs. They were nice enough to combine all three into one GM Honor trait when the Specializations arrived, and they are support-y in a way, although they would help all weapons with their damage now since symbols really started mattering after Symbolic Avenger. Problem is that there's no space for it in Zeal, since Fiery Wrath, Zealous Blade and Symbolic Avenger are mandatory (PvE-wise), and after the buff to Symbolic Avenger there's absolutely no way they'll merge Writ of Persistence with Symbolic Avenger.

tl;dr: There used to be 3 symbol traits in Honor that were merged to one, and there's no space in Zeal for PvE at least.

Fiery Wrath really needs to be made the first minor in zeal. Everyone takes it anyhow and Zealot's Speed is completely pointless and has nothing to do with it's name and I have no idea why it didn't get renamed when they changed up specializations before HoT. Just reaks of no one in Anet understanding the class.

With the Retaliation related buff on Retribution and Righteous Instincts the Lesser of Symbol of Wrath from Zealot's Speed assists in maintaining Retaliation for those buffs. Stopped being useless and it's actually a DPS boost now.
