I have to disagree. If you want those pvp talents in leiu of a longer affliction and mroe crit chance that's fine, but some other things are very wrong with that spec. You're missing thundering blast, which is the whole point of going full lightning. It is a great skill and not getting it when you have the points available doesn't make sense. Shock is never dps optimal and the same goes for chain shock. It's only use is when you need to use an offensive ability but have to move as well. Those rare cases don't merit getting the talent. Also, you should only being using force lightning when lightning barrage procs, so getting rid of the cooldown doesn't help you any while lightning specced.
