7 helmet , 7 orb , 11 FA buff, 5 base, 16 ring (w/o aura aos) = 46 <= CONSIDER 46 as the root point
1. If you use a 3 slot bike you can raise the base by 60. In my opinion much needed, specially in nation war where people are constantly going bm2 / bm3 at the moment. And starting from 11 to 15 it gives 68 to 98 defense.
I think, 60 m atk + 68-98 def > 10% cd 5% amp 3% rate - just my opinion.
2. Nation war, approaching HNR 19 and above in the long run is 7- 10 % resist rate. These are the two things that bother me.
So here are the three options :
Option A : Two rate rings
Compromise 15-17% cd but gain 61% rate. Pushing the max rate around 60 and go for another rol2. And during aos + aura just switch both rings with cr2/3 (in the long run) : Max rate from : 3% aop 3% rune 3% pet 2% bracelet.
46 + 15 = 61%. Or AOS + Aura replace BOTH rings with cr2/3.
Option B : Find another 7/40 or 7/7/24 Wep.
Compromise 14 m atk for going topaz instead of siggy. Find another + 15 , 7/40 orb in topaz. I have seen two others being sold, one in 24/7/7 topaz and other a 7/40 pherry +15. But the pherry has too low a base, loses 30 m atk. Topaz is more reasonable, losing 14 m atk at +15. So the solution is somehow come across another rate scroll someday and push a 2-3% rate on pet. 46 + 10 = 56. I can live with that in nation wars. Again AOS + Aura , switch the k. ring with cr2/ cr3. Right now I don't have any alz to buy anything else. But may be that can come someday.
Of course, this is very expensive. But it's something to think about in the long run.
46 + 7 + 2 pet = 55% rate, In AOS/ Aura replace kell. ring with cr2/3.
Option C : 4% rate 40m bike
Compromise 20 m atk, go for 40m atk 4% rate bike and 3% orb Bad for bm2 + aos for loss of 20 m atk. But still reasonable because in scenarios like nation war / dungeon you can save some sp by not going aura.
3 +1 rate orb , 3 pet, 4 bike. 46 + 4 + 4 + 3 = 57 and lose 20m atk. In AOS/ Aura replace kell ring with cr2/3.
Option D : Keep the kred, get a 3% rate orb
3 kred + 3 + 1 orb 2 pet. 46 + 3 + 4 + 2 = 57% rate. AOS / Aura replace kell ring with cr2/cr3.
----------------- any other options ?
The Question : If you were me which one would you choose and why ?
