DPS Vanguards are all about mobility than actual DPS. (Imo) I usually play a tactics build. Now that the assault specialist abilities are all 10m. Your in melee range anyway, so why not play the melee vanguard DPS tree? I can usually get 6K High Impact Bolts with my stocktrike 5K crits. So if you do that, then you can have over 11K crits every 10 seconds. This is all PvP, PvE you can roll either builds. (AS is more suitable)
