They're discussing initial balance changes in response to the big patch
Cliffs:
- infestor: nerf to fungal area of effect (which had been buffed in the patch), *can't fungal while burrowed* (ouch!!!!), reduced infested terran range
- oracle: 6 seconds longer to build, slight damage reduction vs light so marines/hydras can counter better
- shield battery: increase cost from 75 -> 100 minerals
- ghost: cost change from 200/100 -> 150/125
- terran miscellaneous factory tech lab upgrades are cheaper (drilling claws, rapid hellion transformation, faster cyclone lock-on firing)
One thing I didn't appreciate until playing in the new patch is how much better the disruptor is now that it hits on impact and not after a specified time period. It's way harder to micro against and way more of a loose cannon sort of thing (i.e. I could chase down a disruptor with a bunch of units with no fear if I knew the units could kill it before its nova would explode; now if I'm chasing a retreating disruptor it could wipe the **** out of them if it comes off cooldown, or do nothing and die if it doesn't)
