I do not believe you understand correctly how stats and element relate to on target damage. Element can be a MAXIMUM of 24% dmg boost if you are 240 element over your targets resistance level. If you have 500 element over the target's resistance level, you still only get 24% dmg boost. There is no negative dmg penalty for being under the mobs element resistance.
To the levels stated:
110 = 1380 element rating for max dmg boost - This means you need a minimum of 1140 atk element to begin adding element to, because 1140 gets 0% dmg bonus.
112 = 1530 element rating for max dmg boost - This means you need a minimum of 1290 atk element to begin adding element to, because 1140 gets 0% dmg bonus.
114 = 1680 element rating for max dmg boost - This means you need a minimum of 1440 atk element to begin adding element to, because 1140 gets 0% dmg bonus.
116 = 1830 element rating for max dmg boost - This means you need a minimum of 1590 atk element to begin adding element to, because 1140 gets 0% dmg bonus.
You say you have no clue how to get high element with low lvl, min gear. I 100% agree with you, this is why I DO NOT recommend ever speccing element as a dagger, ever. It is very difficult to maintain the proper element for a boost without a 999 element weapon. For this reason, any other stat is better to take bc those stats guarantee dmg in every situation, but just a situational one.
Now lets discuss stats. Stats have a 1:1 ratio on their listed % and the dmg increase on target in %. For example, as a rule of thumb, one can be safe to view 1% patk = 1 % dmg on target, % p atk crit dmg = 1% dmg on target, 1% p skill crit dmg = 1% dmg on target, 1% p skill power = 1% dmg on target, and 10 element = 1% dmg on target in the correct scenarios.
I have tested this further, with max gear in a very controlled manner to show the following stat relationships:
1% Patk = 0.8530% Dmg on Target
1% Patk Crit Dmg = 0.9431% Dmg on Target
1% P Skill Crit Dmg = 0.9592% Dmg on Target
1% P Skill Power = 1.1147% Dmg on Target
10 Element = 1% Dmg on target (if within 240 element threshold)
Now, you speak low end dagger, I assume this is 105 to 110, but then you reference 110-116. The point about element is its a maximum of 24% dmg boost in the right situation. Most daggers do not reach high element thresholds. Especially exalted gear daggers who mave have an R99 or R110 +12 pve wep. They are probably in the 700-900 atk element range, maybe 1k.
Row 1 element over patk may help in a very unique situation. But if this dagger is sitting around 800-900, even 1k atk element at lvl 110+, Row 1 element does nothing for you, ever. It literally will not increase any dmg output. Row 1 Patk will always give dmg output, roughly +3-4% dmg on everything you target.
I never had the proper element for a zone once I was 113+ without using roses etc. Because of this, I built my toon around not needing this stat. Daggers stack both crit dmg's on their blows, their dmg output on target can be scaled to insane levels if you stack the 3 top stats for othel: p skill power / p atk crit dmg / p skill crit dmg. Patk is added afterwards because it is still damage.
Even if the 40 element applies to give you dmg, you get 4% dmg. If you apply 4% patk, you will see pretty close to a true 4% in dmg at low and mid lvls. It makes no sense to take this if you truly care about dmg on target and have to choose between the 2, which as a dagger, you do.
Berserker Blessing is fine if you have no other dmg increasing AP to take. That extra % wont matter unless we have an xp event. Its a wasted opportunity if you can slot more damage for ever situation.
Your comment about Berserker's Binding Attack is just wrong. Immobile Opponent = Shadow Chased / Bluff / Stunned / Etc. 75-80% of the time you are attacking a mob that is immobilized. You want a 10% dmg boost in that situation.
Even if you consider a party atmosphere, like neutral zone, ketra, etc. Many tyrs exist who will aoe stun the pack of mobs. You are typically always hitting an immobilized target in the game, especially in lower and mid levels. To not take this would be silly for an othel as your dmg is based on having the rear which requires an immobilization debuff.
Maybe instead of insulting people, you should attempt to have a discussion. You might educate yourself in the process.
