we are talking about (gear)
its from the gear it self read the gear stats make an int set make a str set. its simple count wich stat will increase more int in the int set or str in the str set. thats why i listed the gear im not arguing int vs str. im just listing the pure facts of why people do it. its not a big increase over the other but if im goin to optimize my gear this is something i would take into consideration before i start putting materia on gear because like you said you can place int or str equally on gear thats why before you start putting on materia you optimize your gear and if im gearing my pug i would be ignorant to just stack int because on the patch notes it say int 1st damage and for one ability (blind side). when in my opinion str gear still have better overall sats on them then int gear like dex, atk, better def, evasion,Hp,vit. lancer prime example most stack str not pie but what is the 1st damage modifier pie
Example1 body
Rainmaker's Tunic
Str : +6, Mnd : +6, Attack Power : +4, def +128
Felt Bliaud
Int : +5, Mnd : +5, Magic Accuracy : +5, def +111
so your saying having +6 str and mind, +4 atk, +128 def isnt overall better than having +5 int and mind (1 point less), magic accuracy....(pugs dont use) and +111 def (17 less def on a close range fighting class) maybe the way i think is a little elitist i dont know but it seems all around pretty obvious what gear you should put on and the only way i would even consider the int gear if only like you say the int to damage modifier is higher than str and it would need to be a very big margin not 1-2 damage like 15-20 damage over str which it is not
Example2 Legs
felt gaskins
MP : +24, Vit : +4, Pty : +4, Def: +82
Felt Trousers
HP : +23, Vit : +6, Str : +4, Def: +130
....really do i have too? simple version def alot higher it actually gives you more damage more health aka all around better survivability or you can have your buff last a couple seconds longer....
i have yet to say str is better than int and im not goin to say you should stack int over str its a balance and piety is alternative stat if you put str where your putting your pie you would increase your damage by pure fact and funny you say dex vs pie on archer because no i dont have a pie set but its not because of my damage. on my gear i have pie where i could be putting dex because its a balance but guess what i do have a attack power set that i switch out with my dex gear depending on the fight and my attack power set has over all giving me higher dps then just stacking dex....which is why i say that finding out the ratio from str to atk is something worth looking into before you yell stack int to everyone when its coming from word of mouth and basic observation. stat wise dex<pie<atk is what peoples say but living proof the last stat that you should focus gives me the most overall damage 50+ atk golves vs 30+ dex gloves on ifrit bow and crab bow 23+ dex
