I tamed the Son of Hakkar when i was level 60, 3 days ago. Since then he has not gained a single level of Loyalty (still rank 1) despite me keeping him ‘Happy’ (green icon fed) consistently and even unlearning his talents twice.
Ive been out killing high level mobs with him whilst well fed.
The added kick in the teeth, since i unlearned his abilities, i cannot re-learn his lightning breath ability at any rank so he’s pretty much useless now.
Im not sure what else i can do except abandon and re-tame which i’d rather not have to do as its fairly time consuming and I have already wasted so much gold on keeping him fed with his never moving rank 1, Rebellious, loyalty
mh, i cant find anything specific on the internet to it except reset talents once you got lightning breath rank 6 and kill mobs that arent grey to you while hes well fed and keep on trying. sorry. maybe someone else knows how to solve the problem.
i found this on wowwiki, although im not really sure how relevant it is for you tho.
Loyalty gain
To gain loyalty required both xp gained and time spent. The following table was found by [Mania’s Arcania]. Basically, to gain a loyalty level, your pet needed to, no matter what, gain at least 5% of the XP you, the Hunter, needed for your next level. This was required even if your pet was your level (which means they weren’t actually gaining the XP). But there was also a time component on every loyalty level past Unruly. For example, to get to level 4 from level 5, you not only needed the experience gain, but an hour had to pass. This, as Mania says, is why sometimes your pet would ding loyalty while you’re standing around in town-- you had gained the experience, but the time had to pass as well.

no idea why you cant re learn the abilities though, maybe its bugged and its worth trying to write a ticket about it.
