Lockdown the Carriers then use EMP, Carrier's aren't dodging nothing. And, the observer(s) can be taken out with a simple Scanning Sweep or a Science Vessel + Wraiths. And, bring in a fleet of Valkyries, and they take out the Interceptors + Carriers like nothing. It is very possible and easy for Terrans to effectively defeat 24 Carriers. Plus, EMP takes out not only shielding but energy so the Arbiter won't have any energy to use Stasis Field AND can't cloak the Carriers because the Sci Vessels are there. Lockdown + Scan Sweep + EMP + Valkyries make Carriers easy for Terrans. EDIT: And if I'm not mistaken ( I might be wrong ), Restoration from Medics relieves units of Stasis. Again, I am not too sure that's right.
