Depends on your own spending preference. Ask yourself... why did you apply for this card? Is the current limit enough for "your spending during offers"? Is there any unique feature that isn't available with any other cards that you hold in your portfolio?
Just like IDFC increased the limit in less than 6 months, after your recent request, RBL may increase the limit too. So, you may consider these factors or any other factors that may be unique to you before deciding.
