Does anyone travelling in Business Class notice this? or it is just me?

You could be right. I am seeing bulkhead windows taken a lot-could be blocking. Most single travelers would take the aisle, especially on planes like the 787 where you have to step over your neighbor.

Aircraft type? Routes?

I agree that more seats are routinely blocked than I recall being the case. I noticed on the 772ER BKK-AKL for mid-Jan that the following were blocked (and appear to be routinely so):

11A/B, 11 J/K, 12E and 14E.

I made a request to the Gold desk for 14E to be unblocked and allocated to me. This was so that it could map into the 'honeymoon' seat if the 773/359 was brought into service on this route. Staff said it was not possible as 12E/14E are designated for wheelchair pax.

Downstairs on the 744 sees the following blocked:

22A/B, 23E/F, 24A/B, 24E, 25E - presumably for the same reasons (exit row and wheelchairs).

Window seats could be blocked if there is a HVC in the adjacent seat. I assume these all become available at T-24.

I looked at 10 random dates in Oct and Nov.
If window seats not available it seems mostly pax have allocated seats in window and/or E/F honeymoon seats.

The standard 'blocked' seats appear to be 11D/G, 12E, 14B/J, 25D/G.
