This is how I think Javelin needs to be.
Remove the standard straight rocket shot. And make her guided missle only. Decrease the area of effect and damage just a tad so its not an easy insta-gib like it is currently. This would make her fit in more as an air support merc. And would force her to be vulnerable to guide the missle. You know...the same way Kira is vulnerable when guiding. Also increase her cooldown, and give her a better audio and visual warning to the guided missle before she shoots
Why those suggestions? Because all the other air support mercs cannot use their ability to instantly gib someone in a ground battle in one second. The assault mercs cannot either. All the other air support mercs have to take time to deploy their air support, and then wait for it to reach an opponent. And those mercs also have obvious sounds warning players long before the air support arrives. As well as a colored beam on the ground warning of location.
Seems the devs were caught in two minds when creating Javelin. They made her a very good fire/air support merc, that's also a very good assault merc. They give her a straight shot that insta-gibs 1 or more people every 30 seconds. So shes basically what Fragger used to be...without the 3 or 4 second cooking time he has. And without the red trail or loud beeping/chiming noise that Fragger and Nader have.
Dunno why devs thought it was a good idea to turn an air support merc into an overly efficient killing machine that outkills Fragger now...can instagib with a non-air attack (they nerfed this for all other mercs a year ago) along with her ammo giving ability, where she doesn't have to pause in battle to give herself or others ammo (which every other merc has to take a couple seconds to drop ammo).
Make up your mind Devs. Is Javelin primarily air/fire support....or is she primarily an assault merc rivaling Fragger's potential?
I have more thoughts on her primary gun, primary melee and ammo ability....but that's for another thread. But they all add into her being way to good at rivaling both the best fire and assault mercs of the game.
