PVE death and usage deterioration is good imo. I never run out of stuff basically, even with LK 1, having weapons blow up in my face sometimes. Note: I use Fast Shot spammer, that I believe is more cost efficient than most builds, at least on amo and weap deterioration.
Leveling to 30 is not that hard nor slow, unless you gimp yourself in every way possible, like Jinx, only melee, etc. Don't know about further, but you can have a decent character by 30 that can both craft and fight. What's the aim here, level 150 in 3 weeks after wipe? If you chose a 1 IN build, well, live with the strain, your choice.
Bullet repartition is strange, sometimes I miss target and hit another one instead, like 45 degrees to the right or left of original target.
+ Gun runners Mutie quest is too OP in rewards/loot, do that every day, it's quite fast, and your wealth is ensured.
