Windwalker Insignias-oddity

armor +5 (when effected by 1 or MORE enchantment spell)
armor +5 (when effected by 2 or MORE enchantment spells)
armor +5 (when effected by 3 or MORE enchantment spells)
armor +5 (when effected by 4 or more enchantment spells)

in my opinion should be

armor +5 (when effected by 1 enchantment spell)
armor +10 (when effected by 2 enchantment spells)
armor +15 (when effected by 3 enchantment spells)
armor +20 (when effected by 4 or more enchantment spell)

Here's the problem - the game probably counts 2 enchantments as also satisfying the criteria for 1 enchantment. in other words, having 2 enchantments on you would trigger the "when affected by 1 enchantment" criteria AND the requirement for "when affected by 2 enchantments"

Why the hell do we care? There is no difference.

The current insignia conveys the stacking action perfectly. How you'd like it written would lead people to believe they're receiving +50 armor (not the intended +20 armor) for 4 enchantments because of how Anet writes everything else.

Why aren't you also complaining about Minion Master's, Anchorite's, Undertaker's, Prodigy's, and Shaman's?

Pretty much what I was going to say, without the unescasarry flame bait.

Windwalker's

in my opinion should be

Wind Walker's

The way it's written right now is ambiguous. People have found a number of descriptions to be that way.
It should have just said +5 AL for each enchantment on you, max (20 AL).

I think that they stack;

1 enchantment = +5 armor
2 enchantments = +10 armor

and so on...

and yea, it should have always been "add 5 armor for each enchantment on you"
