T3 is totally out of the way from T2 and T1. If there is no airside transfer (I don't know if there is), it is very time-consuming passing through immigration twice and security once and travel between the terminals several km apart.
As moondog said already - only HU has two-terminal operations, and that's T1+T2, the ones which are connected next to each other.
