What do we think about the WASP launcher?

Topdown attack is a small Airburst or you take the mini rockets. They dont seem to kill heavies so what role does it fill?

Any weapon (AC,Mgs,Nade launcher,Flamethrower etc.) is way more effective in the anti medium role and most of them can kill heavies fast.

While using it on bug breaches i saw a lot of explosions...but the biggest killstreak i got was x3....while spamming both attacks near a supply drop. It just feels like a mini airburst launcher with a low ammo count.

So how do you use the WASP to make it work?
