[Gunslinger] Burst Fire; the noob trap.

I've recently noticed that the first 10 levels of this skill are arguably a massive noob-trap as before level 11 this skill does less DPM than Double Shot.
Double Shot at level 20 fires two shots with 130% damage every 0.42s with booster (0.48s without), while Burst Fire at level 1 which fires three shots with 95% damage every 0.69s with booster (0.81s without).
Double Shot ends up doing ~619%/s damage with booster (~542%/s without). In contrast to Burst Fire's 413%/s with booster (352%/s without). I understand level 1 doesn't need to be significantly better, but as is it does less damage per hit (so monster defense is more of a hinderance), less damage per second, and making it harder to pin. All while increasing ammo usage and using more MP.
To add to this, Burst Fire isn't an active skill, so you cannot just go back to using Double Shot having realised your mistake as Double Shot is now Burst Fire.

I'd like to suggest this skill's damage be changed so something along the lines of:
Level 1: 152%
Level 2: 154%
...
Level 19: 188%
Level 20: 190%
This would leave it with the same damage once maxed as it currently is (as this is acceptable), and makes it a small margin better than Double Shot at level 1.
As per the suggestion, Burst Fire at level 1 would now deal 661%/s with booster (~563%/s without).

Of course I'm welcome to alternate suggestions or implementations, but I would like to see this changed as all it does is make the skill worse for anyone that isn't aware of how it all works.

Thanks for reading.

Edit:
I have just realised I imagine this skills scaling wasn't so bad when Double Shot was two 80% hits, but now that it's been buffed Burst Fire falls behind heavily.
