I'm glad to see OOO is adjusting T3 lockdown. The added health will certain help.

That said, I would rather have seen an increased in the effectiveness of defense. Right now, it doesn't matter if have any shadow or piercing defense because you will die in two hits no matter what. With more health, it still won't matter, you will just die in a few more hits.

Also, I hope they increased the rate at which guardians heal people. Before, it took a long time for a guardian to heal people to full health, without a change it will be even worse.

Finally, I think nerfing swords would have also helped balance things more than just increasing health.

Of course, OOO has been known to make changes not mentioned in the release notes, so who knows, they may have done some of the above already.
