It's getting LHB from 15th May, in 1 newspaper it was written as 15th April rest in every news it's mentioned as 15th May.
It has become yet another victim of Infamous Rake Standardization by IR. That's why reduction in SL class and increse in AC. The thing that I didn't understand is that in conventional rake it has only 2 GS but in LHB they increased it to 4, instead those 2 GS should've been 2 SL making them 9 in total that would been much better.
