I have tamed numerous of these on th cluster I play on(5x taming). I have found them to be extremely easy to tame, except when they fly into a loading screen and buck me off. Otherwise, I use a skiff to grapple them. Once grappled you can use HLNA to scan the stats which allows you to easily see its health to avoid killing it for the tame. Being that they cannot attack while they're grappled with the skiff I drop their health with a combo of sword, pike, pick, and fists to get it very low health. After which you can release it and using the tek suit speed boost just tank the breath attack and jump on its back. Don't tank too many as you'll eventually get knocked out. Can mount the skiff to use stims or healing items. Then it's just a matter of timing the feedings properly, which just watch the prompt at the bottom and not the actual barrel roll. The only thing I haven't been able to figure out is how to reset the taming effectiveness. The lvl190 I recently tamed bucked me off and I tanked the breath a bit too much and passed out. She nipped at me until I woke up and when I remounted her, the TE was at 99.4. Ultimately I tamed her with max effectiveness, but I've chalked it up as a fluke.
