The range on it is fun as far as I know, but I'd like a way to easily tell how far away the person needs to be to get hit. Something like when you are shooting it have the hit section of the beam a lot brighter. I don't think everyone wants to spend time in their base testing how far it is and learning it.
it makes a different noise, animation, and lights people on fire when it hits them, what more could you want?
You also learn that maximum jet gun range effectively changes quite drastically in medium to high latency games. IE: You'll hit someone with the beam and make a singe sound, but there will be no sparks, and they won't catch on fire for 1-2 seconds.
Tom's right though. I have played the Tank enough to know how long his jetfire is. An easy way to tell is to practice on bots. Also yes, latency has a bad effect for us Jetgun Tankers.
That's all well and good for veteran tanks, but shortening what you see of the beam to what actually can hit things would help reduce the sharp learning curve of the tank.
Fun Fact: A Tank with Gold skill recovery (possibly less than gold) can infinitely shoot a jet gun while walking down a lane by timing deploy 3 with the draining of the clip. IE: Walk down a lane while shooting a jet gun, deploy with about 30% clip left while still shooting, it will regen to 100% clip from around 5% clip, undeploy as this happens and keep walking. Rinse and repeat . Infinite jet gun without being stuck to the ground (for more than 2 seconds)!
Not really, considering constantly deploying in the middle of a lane like that will earn you instant headshots/head crabs/ ground zeroes from anyone with half a brain. Plus, death blossoming is way more efficient in pushing, the tactic I described has no real practical use other than being obnoxious.
