Two small suggestions.
1.
The first one is an idea I had for a block for Single Blade. The animation would probably be close to Guard, but it would be based on Parry. With a different advantage of course.
Parry
Maintain
+ Self damage reduction
+ For 2 seconds after you begin blocking, you will return a portion of one incoming attack to the attacker, up to a maximum damage. After activating Parry (if you deflect an attack or not) you cannot activate this effect again for 5 seconds (you may continue to block as normal).
My proposed advantage is that while you're maintaining the block if any enemy attacks you and they don't have any bleed stacks, they gain a stack. If an enemy attacks you that has a bleed stack your block refreshes the stack.
2.
My second suggestion is to make the new stance that the Ritual of Arcane Summoning pets use available for players in the tailor with the other stances like Heroic, Average, etc. I've put a reference of the stance in a link.
New stance reference.
