Hello. I didn't know the block "title combo". In the beginning, I didn't understand :-) because for me it was just a title and a navigation, without connexion.
For exemple, I'm trying to customise the header and the start of post and page.
I specify that I do a theme based on basis.

I  remove this block everywhere and change by a simple block title.
The other reason for removing it is that the place just after the title (for messages) is not practical for me.
 
I create a region "admin-secondary" at the top and put messages in it. 
It's more practical, i think and keep the design "outline".

Last thing, why keep title outside the <article> (like in Drupal) ?
I don't see the interest of that ?
An article is a title(with header or not) + metas + content + footer(tags and share)
if i refered to rules of html.

I think it was easy to customise the start of post and page to put date before title, but if i look at the template (node.tpl.php), i have curious thing (h2 for title, date in >footer>) and it's not easy to put the date at the start. Do i need to create a custom module for a block date ?

I found a simple solution... In node.tpl.php i put.

<?php print render($title_prefix); ?>
<?php if (!empty($title)): ?>
<?php if ($page): ?>
<h1><?php print $title; ?></h1>
<?php endif; ?>
<?php endif; ?>
<?php print render($title_suffix); ?>

And i put the date in a balise <div class="entry-metas"></div>

Choosing to not use the "Page title combo" block on content can also be helpful if you want to arrange the "Page tabs" menu and "Page title" differently.
