[Plugin: WPML Multilingual CMS] main disadvantage

i think main disadvantage of this plugin is:

impossible to use different slugs for different language versions (of same post/page), instead of it user have to think out a universal slug that looks good for all languages and because of that slug is same additionally language identifier addition to slug is needed like “/en/” .
