Need some helpFollow

Hi,

This being my first post on this site, I might as well make it a question regarding the warlock.

Any ways I have been playing on World of Warcraft for a good 3 weeks now and have already made it to level 30, at the present moment I have had to respec my warlock because I was not overall happy with the talent tree (mostly using destruction).

Though now, I have started going into the battlegrounds and am now considering grinding to get to the level all my friends are at (Around 45 to 65).

The problem is I originally thought the felguard would be a good choice but now I am not sure if I should use it.

I am planning to Respec my Warlock again (hopefully this to be the last time) but want it to be good at the following criteria:

Questing
Grinding
Battlegrounds

I want to use all three talent trees to achieve this

At the moment I feel my warlock is useless.

This is its current build:

I got a feeling it aint great.

but any comments, help, info, whathaveyou would be most appreciated.

Regards

and before I forget, my Warlocks race is Undead/Forsaken

Ok, I took your ideas into consideration, I also decided to see what I could do with any remaining points till I get to 70 and this is what I came up with for my build:

Would this be suitable for what I aimed for?

and also what should I prioritise the most with each talent?
