Tyr has def debuf, but its only 10% A-frame (Gawain EX skill is 20% A-frame, but then you cant get Arthur's atk up, so its up to you what to get) However Tyr will still hurt quite a lot, if you burst her while enemy is stunned.
Considering all that, and since debuffs>buffs, i, personally would go Sol+Joan (-40% atk debuff, and if we add to that Jorm's summon effect, we get to atk debuff cap of -50%) with Gawain's def debuff, Belobog (def buff) Shiva (atk buff) and Artemis if you have multiple "Shining assault" skills, or going against wind enemies, otherwise Tyr.
I'm using d'arts EX skill right now, ATK and DEF down is pretty strong and stacks with tyr's, I also think that puts me at the attack debuff cap. That skill seems pretty good for where I'm at, I'm not sure if the investment in the Arthur line is worth enough to change skills from that. It seems like it comes down to shiva vs belobog, and it just depends which i'm fighting would be more worth to have around. My weapon grid isn't perfect so it's not a huge deal yet.
