1% Crit chance seems weak but so is 5% base damage.
but when it becomes 30% crit chance, it's as strong as 150% base damage.
One chance out of three of slightly increasing damage is as strong as multiplying your damage by 2,5 ?
Wut ?
When you start abusing multi-hit attacks like Arrow storm every fight, the extra crit chance goes a long way, especially with 200-250% crit damage later.
My high wit ranger deals as much or even more damage than the max fin ranger (and dumping into wit now) simply because he has 20% more crit chance and right now, at level 17, a long distance balistic shot from the highground is a 100-0 to most enemies if it crits. 44% crit chance on him atm means I have a rather high chance of killing an enemy in only 2 AP instead of 4 compared to the 23% crit chance on the high fin which is not that reliable.
