You're confusing me with your last post. Are you saying you support what you wrote above or not.?
I wouldn't mind to have what you say, but I wouldn't mind an "affirmative action" for president to gurantee that TCs have their fare share of presidents either.
How do you propose to do that anyway, by telling the GC's, sorry, you must all vote for a TC this year, because it's their turn to have a President.
If a TC was not a president during the last 4 elections then it will be required that all President/ vice presidents combinations should a TC for president and a GC for vice president.
As long as the Parliament is protected for both sides in passing or denying legislations, I don't think it's very important who the president is, as long as, he is not given powers to by-pass the Parliament.
President has certain powers of his own. He is not totally controlled by ther parliament.
