From my own observations:
Coordination - its a decent stat, ive got no problem with it giving AP as there are other stats that also grant it and there is not much difference between the average and the max. you will probably get to shoot once anyway so every round you waste a couple APs.
Luck - Good stat, can surprise you with extra turns, more hp, and lucky evades, definitely invest some points in it.
Awareness - dumb stat, if too low it renders the game unplayable, if too high most stuff becomes trivial, because of the nature of sequence, min 8 points in it. Why it gives you 2 of sequence instead of 1 or .5 a point is beyond it, it just works to further separate those that have it low from those that have it high.
Strength - p. good stat, 2 points if you are not planning to go in front, a lot more if you want to lead the charge with melee.
Speed - really makes a difference on how far you can go, but it dont belong on basic atributes, should be a skill called atlethism or something. in a game with ranged weapons movement is not that important tho, unless you are the psycho wielding the knife.
Which brings me to my other point, melee fighters are a lot more MAD than gun wielders.
Intelligence - This is related to the issue i got with skills, why the fuck would you ask for 2 points to level skills, and then jump to 4, and then im guessing to 6? why not 1, 2 and 3? it makes no sense. the whole skillpoint system seems poorly thought out and implemented.
Charisma - you have like 5-6 charisma related skills and a main stat in a combat game?
this stat is superfluos, youll more than likely have 3 characters with charisma 1 and one with charisma a bit higher just in case. scrap it, feed it to the dogs, lose it.
This are all considerations concerning early game, maybe (probably) will change the farther you go and stuff will fall into place. Well everything but charisma, seriously.
