Hardly anybody will be doing connections between T3 & T2. T3 will be Ryanair and they don't connect with anybody - including themselves. More or less everybody arriving at T3 will need to go through immigration / baggage collection / transfer to T2 / re-check baggage / re-clear security.
You may get the odd person that is hand baggage only wanting to transfer from Ryanair to another airline on separate tickets, but they will be few and far between.
