How useful is Fel Concentration in PVP?

is this talent even worth 5 points for 70% chance to reduce pushback on drain life/mana/soul? this is my current pvp build im going for http://db.vanillagaming.org/?talent#IE0V0RbZbxuzgxot i feel like i can just recast the spell before it goes away due to pushback and the tick rate doesn't change, at least to not very noticeable degrees. right now my lock has almost 6k mana with my current gear so mana usually isn't an issue. i feel like the points could be better spent in improved drain life or suppression.

Drain life is slightly useful but drain mana and soul are rarely used and even when they are you don't need reduced pushback.  So the answer is no, you should not put any points in that.

In PvP, channeling ANY spell for longer than 3 seconds is just asking to be horribly maimed.

Next question.

Nightfall procs off Corruption AND Drain Life.  If you're going all the way down to Nightfall in the Affliction tree, and you're wanting to PvP, then it would be prudent to spend 5 talent points on Improved Corruption to reduce the casting time for Corruption from 2 seconds down to Instant cast.

Considering that Drain Life falls under the heading of Tracers Work Both Ways™ as far as telegraphing your location AND what you're doing to everyone nearby (an important consideration in Battleground PvP) and the relatively obvious conclusion is that if you're looking to proc Nightfall in PvP, use "Instant" cast Corruption to proc Nightfall for you, not Drain Life.

Things are different (slightly) in 1v1 PvP and Dueling, but even then, you really aren't well served by channeling a spell for 5 seconds if your opponent has any kind of interrupt/stun type of ability, for what I would hope should be self-servingly obvious reasons.
