1st of all I never say warrior dont need int. What I say is in early stages, warrior will usually has higher str over dex and int. Stats will build according to gear you get later, but not in such early stage. A warrior can has a lesser base str if got a lot gears that come str. And in fact my warrior only has base str of less than 50 at level 35, but with gear I can reach 90+, as well as my int too at 90+, all just gear base, without the use of stats potion. In early stage, with just limited stats points, how high you think the stats can reach? Resistance value from armor will be more batter, that why I say scale it according to gear.

Lock pick or not I wont discuss much on this, as different people has different opinion on it. I am those which dislike seeing unopened chests, so I put points into it. An in fact, I still has extra skill points left, since all my needed skill for my ranger is consider max out for my level 10 ranger.

And as for skill selection, those like firewall is still far ahead for him for now, as he just level 7. Level 7 is not actually too low to go into lovis tower. In fact, I clear the entrance skeletons with my level 7 ranger. Its all depends on how you imply your tactics when facing stronger mobs. I barely doing any quest for now, as what I doing now is just clearing mobs in the entire broken valley only. There still a lot quests in early part of broken valley which I havent do yet, such as the jackson murder, delivering love letter and etc.
