Well yeah, T2 was already supposed to be specialized, and a certain amount of them are really specialized, but not enough imho.
We have the sniping ships like half of the AFs and most of the HACs, that have clear bonuses to range. We have the reconships specialized on a second layer of EW compared to their T1 counterparts, we have fleet commandships, logis, interceptors, bombers, covops, etc.
And we also have a lot of other T2 ships that are, as you say, just buffed versions of their T1 hull, like the other half of the AFs, field commandships, etc. And when we think about it, the reconships are just buffed versions of their T1 hull with another specific EW, so eventually, specialized in the sense that the strenghts of their T1 hull is magnified but nothing else specific, making them still good at what their T1 hulls do, and a lot better (specialized) at their bonuses.
So yes, I hope they will do as you say.
