Default Role "Gamer"

I’ve read your previous post and reply about default user roles HERE:
http://support.skywarriorthemes.com/forums/topic/default-user-role/

But I still have a major concern… The Gamer role has the following rights:
edit_published_pages
edit_published_posts
delete_posts
edit_pages
edit_posts
publish_pages
publish_posts
read Help
upload_files

Giving newly registered users right off the bat the ability to Edit pages, posts, published pages and posts? I’ve had numerous newly registered users go straight into editing, deleting and screwing everything up on my website repeatedly. Shouldn’t this be a major concern and major bug issue?

Wouldn’t it be better to somehow create newly create rights/privileges other than giving them full access to edit pages/published pages and posts? Or perhaps put them in the Subscriber role then manual approve them to the Gamer role once trusted or earned? Instead of forcing us to accept the Gamer role?

Also for your response about editing the Default User Role in functions.php for line 187 I have:
/*slider*/
add_filter( 'the_content', 'blackfyre_remove_slider_from_home' );
add_filter( 'manage_edit-slider_columns', 'blackfyre_set_custom_edit_slider_columns' );

/*woocommerce*/
add_filter( 'add_to_cart_fragments', 'blackfyre_woocommerce_header_add_to_cart_fragment' );

Are you referring to this on line 207?

/*role*/
add_filter( 'pre_option_default_role', 'blackfyre_defaultrole' );
