On the skill tree some skills decrease pushback as it pertains to some abilities. What is pushback?

as I understand it ... something like this

 

When you are channeling an attack/heal, each time you're struck, the channeling gets "pushed back" a bit. You can mitigate that with the skill tree reductions, but never completely get rid of it.

 

I just know that when I channel a certain heal, it should take ~2.5 secs. But while taking certain/some damage, the slider keeps getting pushed-back so much that it sometimes it feels like it takes 4-5 secs to finish.

That's it. Good explanation. ^^^

Investing points in the skill allows you to get the full duration and the full damage out of your channeled ability while someone's hitting you. Edited February 16, 2013 by Allegos

Thanks for the info!!! That does help a lot.

wow! all this time, i thought it meant actualy getting "Pushed Back" while casting. I was like "eh? I never get pushed back at all" so i never worried about it lol. Thanks for clerifying this.

To clear things a bit more there is a bit of difference between "channeling" and "casting", but pushback applies to both:

 

Casting - the bar have to fill up full than the skill takes effect, for example "Dark Heal", pushback: when you are struck the bar goes back a bit thus making you cast the spell longer.

 

Channeling - you deal damage or heal for the duration of bar filling for example "Innervation" or "Masterstrike" those skills usually have "tics" in which the deliver healing/damage for example in 3 seconds of channeling you get 3 tics of healing so it end up in 1 tic per second, pushback: pushes the bar further thus ending the skill quicker but does not give additional tics - example: same skill as above, you get struck, the bar goes forward you only get 2 seconds of channeling = 2 tics instead of 3.

When your character gets pushed by a force push or similar ability, the official correct term for that is knockback, not pushback.

 

This is to differentiate which one the tooltips are talking about.

Yes this is correct.

 

Fun thing is the bar on channeled abilities is actually pushed forward when getting pushback, but it is still called pushback, since it is part of the same mechanic that pushes the cast bar back for casting time abilities.
