From the latest ptr notes:

Midnight: Curse of Ula’tek PTR Development Notes

@Linxy

BATTLEGROUNDS

• Developers’ notes: We’ve observed player survivability in battlegrounds making combat less enjoyable.
• Players will now receive 20% less healing in Battlegrounds.

So blizzard seems to agree that survivability from heals was too strong in BGs
