I forgot to mention this Earlier that there is also the fact that most Dapps on the STEEM Blockchain has a 10% Beneficiary Reward which I feel is necessary for them to Run the Service but if the split goes to 50/50 then actually it will be 40% Author Reward, 50% Curation Reward and 10% Beneficiary Reward.
The Delegation Market will Suffer as well because no one will be taking in any Huge Delegations when that will cost them huge Money in the Short Run. Plus I am pretty sure that a lot of Dapps will shut down as most people who still stay in the Platform after the 50/50 split will avoid those Dapps so that they can save that 10% Reward.
