Many of my points have already been said a lot but I'm just adding my voice.
Pistol doesn't feel quite right. Dragon's Roar skill range is basically melee and since you want to use Gunstinger to reload it, there's almost no point to the forward movement since you're already right up in the enemy's face. If Dragon's Roar pushed you back significantly or gave you an evade frame backwards it would flow much better with Gunstinger. To be honest, it's very hard to unseat greatsword as a weapon swap, trying to build even greater synergy with the Bladesworn spec is probably about the only way I'd actually use it.
Booming Fire is ok damage compared to the auto, but it doesn't have much personality. I like Artillery Slash and Cyclone trigger for ranged options, but after hanging back for a second to use them I'm using Break Step to jump in to melee range far more than I'm using it to disengage. For that reason I wish Break Step did at least a little damage on it's path
Players have access to enough stabalize, blocks, and blinks that I really don't know what the point electric fence is. The Gunsaber already has a projectile block, so again, Bulletproof Barrier seems redundant. Dragonspike Mine's cooldown is over 4x as long as the cooldown on Dragon Trigger, it's maybe useful once if you've messed up and got knocked out of Dragon trigger, but flow takes so long to build, that by the time you have enough flow to even bother entering Dragon Trigger again, it's recharged anyway. As far as I can see it's a near complete waste of a utility skill.
The time it takes to build flow is excessive. You already need to be sitting still not doing damage for a while to increase Dragon Slash charge levels. Then to top it off you lose flow / charges even when intentionally cancelling Dragon Trigger. At bare minimum flow and charge value should be fully refunded when you intentionally cancel Dragon Trigger.
This spec extremely underwhelming in group content. Things die far too quickly to keep up with a consistent target. Then when you cancel to move, you lose all progress, even if you're still in combat. Running Daring Dragon and Flow Stabilizer can help you barely keep up, but the damage is pathetic, and eventually you run out of Flow Stabilizer charges, landing you with the problem this spec consistently runs into which is that flow charges far too slowly.
In my opinion Dragon Slash - Force takes too long to cast. We wait enough in Dragon Trigger, skills should be instant. Dragon Slash - Reach is pointlessly weak and only barely longer range than Dragon Slash - Boost. It could at the very least apply some sort of condition or CC.
Finally, canceling Dragon Trigger starts a weapon swap cooldown. This ends up trapping you in Gunsaber at the worst possible time and punishes player choice. F1 should be usable at any time a weapon swap would be usable.
