The loss of the #2 hydraulic system does not, in itself, cause many problems. The only items lost are the right autopilot and the system 2 alternate brake source. The stabiliser trim rate and spoiler capibilty are also reduced.
My main concern would be that the leaking fluid might come into contact with hot brakes on landing, so I might ask the firemen to have a look at it, but perhaps I'm just over-cautious.
