Evasion tank concept, branching from Musketeer.

[Nayto]

A note to this argument about all or none evasion: If you can partially block, partially parry, why can't you partially evade?

A lot of the RNG mechanics is added last to the grand scheme of tankonomics (from what I glanced). Vitality is first before worrying about your blockrate/parry rate. That's why there's little tanks going the DEX build route because blocking isn't reliable enough.
I mean I'd love the idea to become a gun-kata mystic knight but with how Warrior was handled they'd need to double check how to cope on the evasion's tank 'squishyness'.

And warriors are using the same armour as PLDs too. Most likely the evasion tank will be using the same thing as to what LNC wears (chainmail,lightweight plated armour such as bone).

Furthermore while looking for 'evasion tank' concepts on the tanking forum one user pointed it out loud and clear and is the bane of the evasion tank ideal.

The job of the tank is to eliminate chance, not rely on it.
