lol are you serious? skillpoints are one of the most important parts of a build
If you're not going to craft, 3-5 IN is ok, I would use 3 IN for my main, but I want talk properly. I was thinking about 4, but anyway it's 20% that you'll fail spelling. Also that's really annoying for russian keyboard, there're alot random changes, and sometimes you need to say the same phrase like 5 times, to make words readable. So if you have low IN, you better relog on alt with atleast 5 IN if you want to talk to someone, especially cyrillic.
For skillpoints... if you don't have 10 PE, then make 10 PE, because it's more floating bonus to your skill, than IN, if your skill will be atleast ~200%, 6 IN just for Sharpshooter or BRoF, more than 6 IN means you're crafting alt, 1 and 2 IN yes, it's too low, but 3 IN is normal for even sniper build, I think it's better to have more EN than FA/Doc skill. Anyway after CH, IN the less effective attribute for pure combat oriented build, if not take into account perk requirements.
We could lower PE to 6 and put these points to IN, we can then put more skillpoints to BG so the hit chance loss from lowering PE will be catched up, plus we're gonna still have some extra points for FA and Doc left. And the character will talk normally.
PE is already gives floating bonus to weapon, of couse for BG (non-bazooka and non-bozar) it's only 8% per PE, but anyway for high skill PE is more effective than IN. So it's better to take high PE and low IN.
