I think it has its uses in Squads and Scrims/Tourneys (as of the 2.6.0 buff), but outside of that I doubt much will come of it. I have been contemplating what a build could be and I came up with this:

¦



(Straw Boater - No Image)

¦



(Any Recon Shirt)

¦



Since there aren't any Zink Recon shirts (probably to prevent this much Quick Super Jump from being stacked), you would have to scum for a Recon shirt like that and scum for the Hero Replica Shoes since those are Cuttlegear with QSJ main. Of course, you can use other weapons with this build, but it's ideal to use a weapon that has Squid Beakons, so you can quickly jump back and forth between the Spawn Point and your Beakons, minimising time spent away from the action and not helping your team. You can then call out all the weapon positions for a few seconds so you know where they're all heading, and then jump back to help flush them out and get an ace or push the Tower/Rainmaker. I doubt it'll be useful in Zones, since a good team would be able to set up a decent line of defence once they capture the zones, so you wouldn't really need Recon although it would be useful for pushing through their defence if they have the zones and finding weak spots. I picked the Straw Boater to have a little bit of a quicker respawn so you can return to the action a little faster.
I recommend the Custom Dual, because having additional range will allow you to attack from afar, so you don't struggle in fights from the lack of other abilities, a lot of the other weapons with Beakons either need Damage, or stealth play (requiring Swim Speed to get close fast) or have very short range, so I believe that the Custom Dual would be best suited for such a strategy and build. Just my thought on things, and it'll be interesting to hear other people's thoughts on Recon since it got buffed.
