This is my personal opinion - I think only newbie would rush noble at this point of game at 0.5 speed world when there are not good noble targets yet. Nobling 1.5K pointer isn't exactly how I see my first enoblement. Barracks/Stable/Farm - there is pretty much time to go for noble ones pointwhores around you grow.
Guy which has noble has pretty bad area, if 1.5K village is satisfying to noble, have fun with it.
Common sense and simple math fails in the post above.
If you do not have to stay way ahead of your neighbours in terms of troop competitiveness, then academy rush is your best bet:
With farming having insanely high output due W45's settings, you can easily sustain non-stop production of three villages with your main alone. With unchanging, one-packet cost, nobling new villages is as effortless as spitting.
Rather than wait several days for my pointwhores to grow to '
respectable' levels, I would noble those 1-2k pointers and even with lousy, initial lv10 barracks I would probably be four hundreds of infantry ahead by the time you get your second village. Not to mention I will have grown that village of mine by another 500points-worth of crucial infrastructure.
Also keep in mind that despite being pointwhores, those players
do train troops - most of them are turtles with semi-high walls. Terribly slow training speed is very unforgiving toward taking casualties.
2,5k pointer that you lose 300-1000 troops for or 1,5k pointer you pay for a symbolical hundred?
My point is: keep your opinions updated according to reality. This world plays differently than vast majority of previous ones.

EDIT:
PS: Anyone with half brain will backtime his noble unless he goes for 400 point barb. So much about it.
In that case half-a-brain is a very rare commodity among vast majority of TW players. No breaking discovery here ; ]
Who do you think it is, and do you think they will be able to find an ok village to noble
