Hi Sajid,
In an implementation project you don't have anything urgent because this is not live yet and this is why you are not suppose to have urgent changes
also in terms of bulk Normal changes do carry things in a bulk or many transports 1:N.
there is nothing wrong if you follow the standard process at all Urgent changes also follow the short route where as normal which is more aligned to project approach should follow the proper schedule release
You won't miss anything both are technically designed for different reason sufficient for this purpose 
hope this helps
Thanks
Prakhar
