Yes there are better trinkets, but those are not bad affliction trinkets. Spiked Tongue has a good amount of Mastery on it, but its also a single target proc trinket so loses value when you have more than one target. Stat stick trinkets that have mastery and Int, the Intellect will benefit you more with multiple targets than a single target proc. J'im World boss Arcano Crystal, WQ trinket, Nightbane Urn, Helya Bilewater are examples of good stat sticks.
