I would have had ~15% more crits (i.e. n = 5% of my total hits was roughly 17% of my total crits, rounded down because I had already had UL for a bit).
Math suggests that this is nigh impossible. First of all you are not converting all your attack rolls to crits but only hits. The higher the ACC the less hits, the more natural crits, the less overall conversion. Same when ACC is too low. That's 5% of an already smallish amount of attack rolls.
Secondly it doesn't stack additively. Since it's a PL5 ability it's likely that you already have some sort of crit conversion. Let's say you are a Shwashbucker looking for crits. You have Dirty Fighting and Disciplined Barrage and now want to add 5% with Uncanny Luck. This means your overall crit conversion raises from ~33% to ~36%. If we take the "normal" crit dmg modifier and pretend that 50% of your attack rolls are hits then this is an increase of a whopping additive 0.4%. Even in the best case, like +150% crit damage (Devoted + Streetfighter on the edge), only Uncannny Luck as conversion source and 100% hits (ridiculous, but just for the laugh of it) you will increase your dps by 7.5%. Besides the potential for removing underpenetration and the possibility of overpenetration. Still laughable. Do you guys really think this is worth a whole ability point even with the added resistance?
Then there is the duality of the ability. It caters either towards tanks (resistance) or dps characters (crit conversion). If you are desperately looking for ways to prevent damage then you usually don't need the crit conversion that much and vice versa. I would be ok with two abilites: one +10% crit conversion and another with 10% resistance. This should be balanced in regard to the actual Uncanny Luck, wouldn't it. 1 point for 10%. Funnily though: I presume most people would be more tempted to use one of them as they would be to pick Uncanny Luck. Why do you think is that?
And last but not least this ability is universal. You can't judge it after doing one test run with one special build. Even if you logged everthing properly and had verified data.
i mean seriously though at high levels what are you going to use those points on? another ability you won't use due to action economy or resource constraints? e.g. for a rogue i wouldn't pick it over dirty fighting, but i'd definitely use it with dirty fighting.
You know I don't want to sound spiky - but you seriously think that "there's nothing good to pick anyways so we might as well give the player something bad" is an argument against boosting Uncanny Luck a bit?
If you take it with Dirty Fighting you will increase your dps by a laughable margin (if dps is what you were looking for - if you take it for the resistance then ok). It is def. not worth an ability point if you're out for damage. Even Tough may have the potential to improve your dps more - because if you going down a bit later and landing a couple more hits before going down. Heck, Fast Runner will do more dps for you.
We'd lose the tiny D&D reference!
Hehe, that's actually a point for my case.
