StarCraft II - updated impressions

It sounds like heresy. But each new toy has its own strengths and personality. For every fan favourite lost, like the Firebat, a new contender pops up. Yes, the Firebat was hot stuff: scorching entire legions of Zerg. But the Reapers are cooler: heavily armoured infantry that can leap across gorges with their jetpacks, dropping timed demolition charges. They zip into position, lob their grenades, and get out before any defenders have a chance to react.
