The illumina RNA protocol uses random hexamers to amplify the RNA. The thing is they are not 100% random so the beginning looks skewed for base composition, but that's because of the amplification.

For mapping it's no problem. For assembly it might confuse some assemblers. (When assembling I would trim the 5' of RNA, not for mapping)
