Ok first thing this proves u dont know why u making STR character( NO OFFENSE) the point of putting full str or INT is that when ur char is at high levels u are a good PURE STR OR INT . Meaning to say every time u level up i thing 3 (not sure) point are added to INT AND STR other than the 3 point given to u which u can distribute. This characters are basically "TANKERS"
Meaning to say KABLOOMI AND ur dead. No time to think so basically its one shot kill. If u are not interested in such build i suggest going for Hybrid.
FOR A NORMAL MONSTER KILLIN SITUATION:
A pure str wud be harder to kill even if he / she has a weaker weapon because he has more HP.
A pure int wud be harder to kill coz he / she has concentrated elemental power which he can use over to heal quickly or say shoot magic powers over and over again.
So if u like using magical powers over and over i suggest go for a PURE int built:
As for my i am pure str sure do use a lot of MP but when it comes to normal attac i dont even care of using a HP pot . I sometime leave my character just like that and when i come back a monster wud have been trying to kill me but not much HP would be lost as i have ton to spare.
Pure str is not so good if u are doing all the quest assuming u are a regular guy with not so good weapons(mostly bought from npc).
I found solution for this is: Get you levels high by grinding on those monster which u can kill with less effort .
And invest in a good weapon cos effectively u  wont have to buy mp pots
if ur weapon kills for ya. I usually use special elementals only when i think its taking too long to kill the monster.
For example: I was doing chakji quest at lvl 22 now i had to kill 600 (which i did in approx 8 hrs) with a normal lvl 18 weapon bow,
First when i started i used all the mp pots which was kinda cosly but for the last 400 heres what i did
I used the elemental powers (blade + fire + smash seri) to kill the chackji quick then after killing 3 in row i wud rest replenish go for 3 more.
