BEGGAR'S BAZOOKA:
It is an interesting spread weapon indeed; I think raising the rocket amount to 4 or 5 would be good.
Reloading it is the subjective part IMO; if he reloads too fast, its overpowered. Your suggestion about being able to escape with it like a rocket launcher is a good point. I think it should have the ammo expansion, and only the first rocket be INSTANT to load in, but only when rocket jumping somehow. Perhaps, while the soldier is ducking, jumping, and looking down towards his feet all simultaneously. I don't know if that's programmable, but I think it would make beggars balanced.
Another suggestion is reducing clip size, but make the rockets homing after .5 or .25 seconds of being launched. (delay for rocket jumping)
THE ESCAPE PLAN:
Escape plan is good, but not fast enough to escape, even with low HP. Equalizer is good with low HP, but the hale's range is so wide, you'll never get on him head-on. I suggest you combine the 2 weapons. if soldier would equip either the equalizer or escape plan, replace it with the fusion weapon. (Like the medic's custom kritzkrieg.)
