For the longest time I only had one battle pet. Now that he's a few points shy of the 35k cap, I'm still earning surplus experience points that aren't going anywhere unless I throw them at increasing his level, but I'm in the midst of raising a second battle pet that could use the boost. I'm sure there are others in the same boat. My thought for this is to instead have a way of transferring(with a decent deduction) that experience over. Say pet A has 100k exp, pet B receives 50k and 50k is deducted for the transfer. Put a limit on how often it can be done in a given week.

I know a capped pet won't earn any experience so that would make the T13 earning exp a moot point, but the thought is that, if a second pet will inherit the armory and scrolls of the first pet, why not pass on experience points the same way?
