My take on two of the racials. I was initially set on doing all 10, but my time is up for right now.Undead: Wait and see
This is still the best racial in the Pet Battle system, but not by a TON any more. The burst nerfs indirectly nerfed this racial in comparison to the Mechanical racial because the Mechanical pet has much more of a chance to survive the first round. Additionally, the burst nerfs essentially lowered "damage per turn", which slightly lowers the usefulness of the additional turns in comparison to the other racials.
I do not suggest changing the racial to avoid ties unless you plan on redoing the entire win/loss/tie end-of-battle system around it. While I don't think this racial should be nerfed right now, the last thing it needs is to win more battles and the -last- thing you should do is change this, which encourages more and more use of 3x Undead.
Suggestion - Don't nerf it. Don't buff it by "fixing" ties. Just leave it alone for now and reevaluate after making the other racial changes.Dragonkin: Too weak
A lot of people on the forums don't seem to understand this racial or the changes that occurred to it. Originally, it was fine in terms of balance, but it was balanced around a bug (2 turns of the damage bonus). When the bug was rightfully fixed in a later patch, the racial started sucking due to its very limited usefulness.
Suggestions - Increase buff duration to 2 turns, make it also trigger on a kill in addition to going both the health threshold (and make it refresh if it hits another trigger condition), or increase damage gain. I perfer to the first two solutions. For you, the first solution is probably the best because the second one is a little complicated to explain and handle while the first solution is just changing a "1" to a "2".
When blizzard fixed the bug that made this racial last two rounds, they showed us they want this racial to be bursty (1 round, +50% damage). They could have made it more sustained (2 rounds, +25% damage) but they didn't. So I don't think increasing the number of rounds this lasts would be a good idea. I think we're stuck with 1 round on this. I also no longer think it triggering on a kill would be good, because it would remove the usefulness as an execute.
With those parameters, I think the focus should be on when it gets triggered. Find the sweet spot that makes it feel useful as an execute or an opener.
I wouldn't read too much into game design from bug fixes. The programmers probably don't always consult the developers when fixing smaller bugs; they could have just fixed the Dragonkin racial to match the tooltip simply because it didn't match the tooltip.
