Most useful abilities?

What are some abilities that are really helpful in a bg? Currently I am finding that intimidation and oblivion shield are incredible

 

Soften and swap (3) are some of my favourites to have around.

 

Swap, Nexus Aura, Designate: Flagbearer, Weaken Spells, Phase Shift (0 AP gain flying), Battledrum, True Nature.

 

a simple distract will put an end to ..almost.. everything that was or will be mentioned

 

Dispell and detection for sure

 

Very true, it seems that relocation abilities are very popular (understandably so) but distract will certainly throw a wrench in that

 

Attack: X is really useful

 

Depends on what you're playing, whatever abilities will help push your strengths will differ with every BG.

 

Ritual, shatter, boost, commander, defender

 

Invigorate, drive, Seism, blockade, pull, vengeful, vitality: creation

 

soften is amazing, as is nexus aura.

 

If I could give you gold, thumbs, etc. I would.
