I also completely don't get the reason for removing -to hit penalty- for strength and one hander.
Because it is useless (...) it was very hard to lvlup char with low str
[trolling] If it was so hard, then it wasn't that useless

Don't get me wrong.
I like the new penalty. I just think it would work best together with the original one (-20, the test session penalty was an overkill). The old limitation wasn't useless. It was penalizing, but only on lower levels, this is why people ignored it and grind their way through it cursing about the grind, but doing it nevertheless. New one is also penalizing, this time only on higher levels (90% mobs don't shoot arms or shoot them rarely) . If we had both (
-20% + cripple chance), having low strength will be penalised at every level, just as it should be.
I'm afraid leaving the low levels without any penalty (at least I see none) will encourage some strength exploits. Imagine needler char. I'm planning one for my friend and I don't see any reason to put STR above 1. Now until about level 20, he will be able to run around with any gun he wants most of the time (what low level mobs attack arms often? Bandits and?). Later, after level 20, he'll just take buffout and switch to needler (which was the target weapon) - voila, 1STR char with no penalties throughout the whole game.
The same goes for my p90 burster. I can put STR2 and one hander, and use any weapon I want with no problem, until real battles come, when I'll just take buffout and stick to p90 to get max effectiveness.
Yes, I know having proper STR has its advantages now. I like it. But erasing old -20% is a new incentive to put your STR 2 points below requirement, as it isn't really penalising at all. cripple chance penalty + to hit penalty would work best together, cripple penalises pvp and high level pve, to hit chances penalises humble beginnings.
