Ironically, I find Spellbreaker to be my Warrior's best choice for doing damage ; the Full Counter can be great when I'm surrounded. I don't use daggers though, I use greatsword instead ; the burst skill is AOE and much faster than all other weapon.
And, although the armor pieces might be ugly as heck, I'd still fully train the specializations, because, who knows ? Maybe I'll suddenly come up with something to try in the spur of the moment. Not to mention, I don't think I have the time to play so many character ; 9 is already quite a lot for my time anyway.
Also, you only get the weapons and armors once anyway. Let's say, your charr Warrior is the first one to start training the Berserker elite specialization, then only that charr Warrior receives the torch ; anyone else that starts the specialization afterwards don't receive the torch. However, later on, your asura Warrior finishes the Berserker elite specialization, then only that asura Warrior receives the helmet ; anyone else that finishes the specialization afterwards don't receive the helmet.
The PoF elite specialization for Necromancer is Scourge. I'll admit, I'm not a fan of it either. Reaper (HoT) and Harbinger (EoD) are far better.
