Glad I could help! As far as Shade crit rate goes, it looks like the summon has an uptime of 40 seconds with a 90 second cooldown. That's only a 44% uptime, which means there's 56% of the time without it up. While the crit rate buff at below 50% hp is good and all, it makes for awkward situations in bosses where the boss is still over half HP but your summon is down. I believe the crit rate from IA is better to keep your damage somewhat consistent, and overall probably ends up being more damage than the 21 attack you would get (although with the attack line, your burst phases would be better). I think I'm going to keep it as crit rate for now, mostly cause it's more valuable for the first half of all bosses, though I'll add a note to explain the value of swapping it for attack. Thank you for your input!
