That is awesome. I'm assuming it is still level 40 before you can buy ranked but this will help a lot.
Also hoping I can do field respec in WZs. Was thinking yesterday as a sawbones, it would be hilarious to switch qucik to scrapper and go after the sniper that was doing his best to keep me pinned down.
You can respec inside a warzone already but leaving your team without a healer in order to go after 1 dps is probably a very bad idea. I've respecced many times from dps to healer inside a warzone, never from healer to dps.
