Stumble & Block / Parry

Been testing few things with my gladiator and templar and found some rather not so clear things while I was on it.

Whenever my Sword Storm get's blocked or parried it won't stumble my target. On the other hand, even if my Wrathful Strike and Crushing Blow get's blocked or parried, they're still able to stumble my target.

So, bottom-line. Are skills that's suppose to stumble target SHOULD NOT stumble once they get BLOCKED / PARRIED? If yes, then gladiator's Wrathful Strike and Crushing Blow are both bug? If no, then templar's Sword Storm is bug?

Someone please enlighten me on this one. I've tried searching through Google for the answer but couldn't find anything that could absolutely clear things for me.

if ur enemy are templar..when u use sword storm...then cant stumble ur target..thats mean they use barricade

 

None of you two seems to have gotten what I was trying to say.

Anyone out there who understands what I wrote above can answer it? :3
