I'm sorry I looked like I didn't put alot of reasoning into my previous statement. I thought it was unnecessary and that you had some yourself.

The bloodline will be left quite untouched if we do have to vote for a new heir in our lifetime. The only good candidates are sons or nephews of Basileus Antiochos. I imagine, however, a future where plausible candidates are adopted people or greedy son-in-laws. And I know the Basileus foresees this to. Now it's not my bloodline and I won't base my vote on this argument. I did not pose this question to you, but to the Basileus, by the way.
I, now, considering your remarks on the council, believe you think Sarpedon is incompetent. And why is that? Lets reason.
He is right now the best administrator in the Arche.
I know, he does not have any military experience, however, he only received his Royal Army in the last few seasons, leaving no room for him to plan any offensive.
So why then you think he is incompetent? Is it just because of the last petty discussions you had with him, in which Sarpedon was right? As in the other discussions he had with other strategoi this session? For Zeus! He is still a very young man, with alot to learn.
Might his personality be disturbing you then? I'll be honest he did showed me a quick glance of his racist personality today, there's, most likely, not much more to it than a simple pontual rage. He probably seems arrogant to you, but I see it as a young man's reaction at being recently named heir, with time, he'll know is place in the world or he'll place himself above the world. But it is still a bit soon to judge that.
So why is he incompetent have I missed something?

Yes this eddict will increase the rate of civil wars, chaos in the council and anarchy, I repeat I have little against republics. Especially when they are needed. So, lets reason, why these kind of elections could cause so much unrest, well it is simple, the council would divide into interest groups each with one candidate. This is only avoidable, as I said, with responsability. Something that seems to only appear in a few people every other generation. Yes, I know, such also happens with the Royal bloodline. But this time it seems we'll lose a responsible leader, due to some irresponsible leaders who judge competence during trivial argumentations with young men.

Furthermore I don't like the way this eddict is heading to. You look like you treat this like a national emergency and I completly disagree, I hope some do think as I think and will vote Sarpedon as heir. I will vote Yes on this eddict, for its great uses in real emergency situations. Another suitable eddict would be to give the council "impeachment" powers.

Spoiler Alert, click show to read: 
Yes impeachment would be impossible ingame but we can always suicide the Basileus and pretend he was assassinated or exiled.
