A small hotfix patch will be released later today. The patch is going to address some server-side issues, but it also includes one pretty major change to Battlegrounds game mode.
One of the latest additions to the format – Stormscale Siren – will be replaced by Warden of Old. The reason is that even after the balance update, Nagas were still scaling too well, so a temporary solution is to get rid of one of the main culprits. Instead, we’ll get an old card, just updated with a Naga tag. Different changes to Stormscale Siren will be tested internally and the card will return in a future update.
Read the official comment below:
We are releasing a server-side hotfix tomorrow that addresses some server-side issues and also includes the following changes to Battlegrounds:
The minion Stormscale Siren will be removed from the minion pool.
The minion Warden of Old will be returned to the minion pool at Tier 3 (now with the Naga minion type).
Dev Comment: The combination of Stormscale Siren and Tidemistress Athissa resulted in Naga warbands that scaled too large, too quickly. We’ll be playtesting changes to Stormscale Siren internally, in hopes that we can find a version that we’d be happy returning to the minion pool in a future patch.
