Here is John's list:
Here is my initial rating list
The AWESOME (worth spending fate to clear recovery to reuse)
Darken the Sky
Steel Rain
Shield Slam - You get to A) do weapon damage, B) knock prone, and C) push a clock, all without drawing free strikes and for no speed increase. There is no reason someone with a shield shouldn't be using this every attack, especially since it's a Base maneuver and can be combined with even more deadly attacks (Sweeping Strike!)
The GREAT (would want to use almost always)
Edge of the Shield
Entangle Opponent
Juggernaut’s Hammer
Mighty Swing/Throw
Pin Them Down
Point Blank Shot (Goes without saying)
Ranged Disarm - Good use of a 1 shot / fight
Shield Throw - With Air rune this makes for killer Advanced Maneuvers
Stunning Strike - Stunned is a great status effect to give out
Twin Throw
The GOOD (want to use half the time)
Crippling Shot - This is a great 'battle opener' and movement is key in Arcanis.
Crushing Blow - I'd see using this for some good Advanced maneuvers but not all the time.
Long Strike
Slashing Disarm - Good if you are built for disarming
Stinging Shot - See Crushing Blow
Twin Arrows
The SITUATIONAL (only rarely useful or very useful in some situations)
Dismount Opponent - Very uesful when the situation arises
From Earth to Sky - Great trick, but reactive when charged only
Grasp the Blade - Your weapon is tied up during this, so it's situational
Hamstring - It's until YOUR next action, so only marginally useful.
Pinning Shot - Awesome flavor, but it doesn't impose Immobilize and huge recovery for 0 damage
Pommel Strike* - One word: Murders
Quick Reload - For Light XBows this approximates a bow. Others not worth it.
Quick Set
Render Shield Worthless - You lose your weapon with this but it's cool when it works
Shield Formation - Awesome if you plan for it with an ally, but situational
Snatch Object - Love the flavor, can be useful if GM's allow cool things
Throw the Blade - With Air rune, this makes for great advanced maneuvers (Again the shields get the best version)
The POOR (IMO not useful)
Bypass the Shield - The bell curve attack rolls make a +1 not very good for the speed cost.
Rapid Strike - I don't see the point. It's a 1 speed decrease for another maneuver at -3 damage. You can't add this to an advanced maneuver.
Shield Defense - Just go full defense
Shielding - Too many restrictions for advanced
