From the long thread about it we know the level 10 ability is not going to be Beastial Wrath but it could be taming an exotic pet. I have to wonder if Beast Mastery would end up being split if that were the case because extra pet talent points isn't exactly helpful at level 10 (pet talent trees won't be changing much). Of course we'd need to have much lower level exotic pets to tame if that were to be the case, but I just don't see it personally.
At the end of the day it doesn't really make much difference to me what they alter because I still enjoy playing and I'm sure I felt the same excitement and nervousness when they announced agility would equal AP 1 for 1, or when the pet taming skill system was removed and pet talents with family abilities was announced, or thinking about losing mana and getting focus, and so on. Some of those changes I didn't look forward to at first, but they grew on me once I'd tried them for myself or seen them in action so I will reserve judgement until I hear more news at least.
