Full alpha includes being snared for 30seconds.
And BS is still full of blobs and kiting ranged toons... not to mention that snare/root perks and NTs are an insane hard for us.
Melee is such a huge disadvantage and many people tend to forget that.. also agents have a LOT better alpha than enfs. They have lots of uber damage perks and every perk has some kind of debuff aswell.. CS, The Shot, Tranqualizer, etc, etc.
Not to mention that AS that is going to get some love in the upcoming 17.1 patch.
EDIT: Try to feel the frustration when you stand on top of a certain ranged toon with troll form running... and trying to avalanch/stone fist while getting the message that your target isnt in range. It happens sooo often and it totally ruins your pvp experience. If you watch my pvp movie with random material you ll see that happening.. while I could have killed 2 people with it.
