Iron Reflexes + Wind Dancer

So... I'm playing with Mortar Cannon Tactician. I was thinking about some upgrades lately so I looked at poe ninja... and... Most of the top builds use Iron Reflexes (as I do, having 88% phys dmg reduction). But most of them also use Wind Dancer. My question is: WHY? It just doesn't work. As the description of conversion says: all buffs apply only to the new stat (the one after conversion). If Iron Reflexes converts evasion into armour, then evasion buffs don't apply. You can see it in character stats - turning Wind Dancer on/off changes nothing (armour doesn't increase). When you have some flat evasion stat on gear then they will increase armour. But evasion buffs (like +%) won't work. I doubt that so many people are missing it, so I guess I'm the one missing something. Can someone explain?

this might be one of those things where the order of the skills matters. I know for some things the order of the support gems matters so if winddancer is calculated before iron reflexes it would give a buff to armor. I'm not sure if the order of skills matters though

You are right, wind dancer offers no evasion benefit after allocating iron reflexes.

A quick glance at their support gem setup for wind dancer tells you everything.

The majority uses wind dancer to debuff enemies with the wind blast that gets triggered when hit.

Some use it for damage and others put further persistent buffs into it.

It makes some sense, but on the other hand it doesn't. If Wind Dancer is only a "holder" for support gems I could think of many different auras which can hold supports and at the same time bring real benefits. Maybe some Heralds or barrier/armor skills (?) Unless Wind Dancer has really wide AoE (?) Is there a website somewhere to find radius/reach of skills?
