Hey guys finally need some advice as I want to tackle some T3/T4 accessory quests but having a hard time probably coz my weapon grids are not complete.
Reason being much as I tried focusing on one element ( I leaned on water) I actually built all with skills ranging between Skill 6 to 10 only.

Since I considered Water a lot in the beginning I have 2 of the SSR assault weapon at Skill 20 and most SR at Skill 10.
But anyway part of the reason I am asking for advice is to to check again the recommended skill levels for SR and SSR weapons for non "main" elements.

For example on one thread I think I saw Skill 8 for SR and Skill 15 for SSR to see an effect?

==
For my next request for advice is team. Below I list my SSRs.
I personally find that although Light seems the closest to being full SSR, I need a good offensive SSR for it even though Artemis is a good placeholder and Beelzebub buff always helps.
My WATER having the better weapon grid of course damages well as well but not enough.
Also got the Raiko drop earlier and THUNDER always have good DPS so that defense KH seems like good timing as well.
DARK is good too since Beelzebub is there and Sol can be plugged as needed.
Finally for EARTH even no SSR i Have all the SR that can debuff well so somehow they survive well too.
My FIRE works just fine too.

In the end I am starting to get really confused since all can survive except on Accessory quests and really hard Ragnaroks so please help evaluate.

SSR List:
Light - Micheal, Raphael, Sol
Dark - Amon(Unleashed)
Water - Poseidon,
Fire - Acala
Lightning - Raiko
Earth - None
