If he is looking it to use it for RBL specific offers then he can keep it.
Based on what I have seen on this forum and also my wife's case, there should be an LE after 9 months of use.
In my wife's case they started with 32k limit and it was increased to 59k after 9 months, now it ain't much but is enough for most of the domestic flight booking, food delivery and e-commerce offers.
And it is LTF and the 1% cashback is directly credited to statement unlike some other cards that charge yet another redemption charge. So all in all, while it ain't an awesome card it is quite decent for bank-specific offers in my opinion...
