Weapon loses value in M+, due to having exactly 0 aoe scaling at all (ST proc that’s based on casting spells, not instances of damage done). So ok, you’re missing 0.15% damage from the weapon.
Antenna post nerf is a side grade to Parapodia from Eco dome (which one is better varies from sim to sim for me), and can lose out in higher target count sims for boomkin.
Ritual forge is good for burst specs, but Signet and Lilly both exist as passable alternatives. Although for me, with the damage profile the way it is, the trinket is just bad post PTR nerf.
