I agree - T2 should be an improvement over T1 which I very much dislike.

I was mainly thinking about T3. The experience for Y pax is/was rather mediocre, but as a SE I found the experience pretty good: no wait times at check-in, dedicated AC staff, very reasonable wait times at fast-track security, short walk to the lounge, ability to skip the line for the document check at the gate and minimize the the time spent in the "holding pen".
