User blog comment:Fffrikkie/Riot Changing Meta?/@comment-3974211-20151004044031

Back in my day Marksmen went mid land and bot lane was Mage + Support (hence why Soraka previously restored mana and Lulu used to grant AP). Riot is trying to free up the meta - not so much change it. When Cassiopeia was reworked I mained her bot lane. Riot intended for her to have a marksman power curve so I took them to that - and she was amazing. Unfortunately, the latest change to her E's mana refund seems to have been the nail in the coffin for Cassiopeia - she can't afford to trade and farm any more.
