It's more that I focused far more on light compared to the others and they're finally starting to catch up.
Plus I'm not as hardcore of a player as a lot of others on here. Sure I know how to get stronger (usually), but I'm still sitting somewhere between casual and hardcore on how much I grind (I do still have a full time job among other things).
If I honestly had more time and made this game my only focus (I do play 3 other games and I'm making my own as well), then all of my grids would likely be no less than skill lv20. Hell, I'd likely have MORE kami (currently at 172 as of the last SSR guaranteed pulls) and possibly a 100% eidolon or two... this isn't the only game I'm throwing money at after all. I tend to pick them in a cycle unless I can spare more.
In fact, almost all of them have nothing but SSR weapons in fact, I just gotta start leveling them up. Between all 6 elements, I think there's only 1 or 2 SR weapons still there.
But overall, my grids are roughly 50%-70% assault (fire at 90% and light at 127%), each has around 30-50% defender (light at 90% cause dual weapons), and each team has a 40% elem eidolon (fire and dark has 60% cause echidna).
My gacha luck on eidolons is kinda crap cause I'm getting the same ones a lot (might have had a lv100 Fafnir if I never sold her), yet no 100% eidolon was pulled and since I'm a day 1 player... rerolling has long been out.
