No-one seems to have noticed on Reddit but if you connect to the PTR you can download the new patch and patch notes. Major changes in here.
- Regen globe and healing well changes have gone through
- Minions now deal double damage to structures (winning your lane just became a lot more important!)
- catapults got a major buff
- 26 heroes have talent passes (still reading). Dev comment - this is apart of a massive second look at talents that are not picked to improve them, across all heroes in the game in the long run. so lots of unused talents just got boosted,.
- Gardne terror now does 200% bonus damage to structures
Gul'Dan:
Trait: lifetap. Gul'dan doesn't regen mana, he can lifetap to trade 25% life for mana
Abilities: Q Fel Flame, line of fire that passes through things damaging them all
W - Drain life, 3 second channelled DoT that deals damage and heals Gul'Dan
E - corruption - 3 bursts of damage in a line, causing damage over 6 seconds. Stacks up to three times
Heroes:
Horrify - After a short delay, deal damage and fear everything in an AE circle for 2 seconds
Rain of destruction - 7 second meteor spam over a large area.
