So I just did a post patch match:

Change I have noticed so far:
Strikers get 3 hp more over what they had previously.
Recon gets 10 more hp than the strikers
Guardian gets 2 more hp over Recon.
The hearts are now light blue (I guess to heal status) and the shield meters at the top look better.

I think the extra hp for recon & guardian adds WAY better balance. The strikers remain papery but strong in offense, and everyone else can take more hits.
I am quite content with this change!
Thoughts?

new bug: you have to change class to guardian and then to recon to get the hp bonus
