mado has no use for agi unless you want to be a knuckle boost spammer (im not sure how much agi even effects this because i never use it). it sounds like you found a niche with knuckle boost though, and if its working for you as a leveling skill, then that frees up more points for other stuff. Arm cannon lvl 3 does alot of dmg but you need the high dex to support it, otherwise its too slow and you end up losing overall DPS. As for its short range, welcome to the world of Cart Cannoning geneticists . and yea flame thrower is fun as hell but its kind of a pain to use hahah
IMO i would dump the agi and put those points into dex and vit instead. i dunno how youre doing on SP right now, but if 12 is getting you by then by all means keep it. also, a rideword hat might help out out with the healing issue, as it frees up headslots for a pirates dagger, or fish in mouth + slotted glasses (if you can afford all this).
this is an ideal stat setup for a lvl 99 mado:
str 80, 1 agi, 70 vit, 19 int, 90 dex, 1 luk
you would be raising dex vit and luk at this point (luk last for that extra dmg boost).
heres some motivation to get you going:

First of all, I would like to apologise for this tardy reply.
Second, I have finally resetted my mado mech into a proper one, however, the stats implemented to it, is different from what you have suggested. As they are build for my preferentials. My stat build currently is around: 95 Str, Agi 1, Vit 70, Int 20, Dex 90 and Luk 1. My level at the moment is 107/20. For now, I am focusing on leveling my mado first instead of the skills as it is more reasonable to do so - because during turn-ins, people are extremely picky nowadays and tend to focus more on getting the axe mechs than the mados.
When I resetted, I noticed that my knuckle boost is no longer spammable anymore, but it still does the damage it usually gives out. Its just slow really, and yes, it is affected by agi and 50 was the reasonable value it has to have for continuous spamming in my opinion. Also, since agi was already out of the way, when madogearless, I turn into a novice-like mech that has no ASPD. It wasn't fun. I still have some sentimentality of having AGI but in the future, I might restore 50 agi back, if I have stat points left.
That video was sure motivating, I was impress that the NB was like the KE of the Priest class.
Also, after reset, I have re-structured my skills. The only thing that had change in it was that I had discarded, the useless (IMO), Upgrade Weapon Skill into Lv.10 HSCR, Lvl 5 Shattering strike, lvl 3 Max.Power Thrust and lvl 10 Mammonite. However with those, implemented skills, I had forgotten to take the Item Appraisal skill!
I was not please about it, but whats done is done. Sigh..... XD
