Not the largest sample set, I know... I've just spent some hours plugging away at the Twisted Weald and Lord Oaks spawns in Ilsh, with my mage, and my tamer. I've maybe killed twice as many mobiles with my mage, but nothing higher than a shadow wisp, and got 4 SoTs. On my tamer, with an unbonded Greater Dragon sad4 or an unbonded Cu, going up to the centaurs, I haven't received any. I'm not complaining about only getting 4, because I'm dead chuffed about that (little things... ). But I was working the spawn with another tamer, who also hadn't got any. I know it could be RNG hate, but I have to wonder whether taming just drew the short straw when it came to SoT drops. I haven't read anything about it though, so I wondered, and hence posted.
