I'd say that if you want the game to be more interesting, harass units need to be bullshit and OP. Seriously, we aren't even approaching the power of reaver/storm drops, mine drags, old muta harass, lurker drops ... It's easy to yell "nerf!", but people need to figure out how to deal with it. This is probably the only period where they can do it "safely" without endangering the proscene.All the harass units are very bullshit right now. Oracle is almost as bad as Mutas and Hellbats, it kills combat shield-less Marines in two hits so you can beat like 6 Marines with 1 Oracle. The high DPS also lets you easily destroy any kind of early game attack using Zealots to tank for them. If Terran wants to expand, they have to get like a 6 minute Engineering Bay and two turrets in each mineral line to not just outright lose to Oracles, because Marines just do NOT cut it. They're also the best possible answer to Hellbat drops, Hellbats are light so they get slaughtered.
Half the power of econ harass in BW was because even if you killed nothing, the opponent still had to spend a billion APM cloning all his workers back on to seperate mineral patches. We don't have that in SC2.I'd say that if you want the game to be more interesting, harass units need to be bullshit and OP.
