What have you misunderstood? I listed all gothic influenced bands. Right below, "True gothic metal is something you've never heard if you're under 30 years old".
In fact, NONE of these bands are 100% gothic. not even Lacuna.
You're free to get your own gothic definition.
My "own" gothic definition is just the definition that was applied to actual goth music like all the stuff I've listed in this thread already which was mostly released well before the concept of "gothic metal" even existed. Gothic metal as far as I'm concerned is mostly a superfluous and almost non-existant genre. Bands like Katatonia, Sentenced, Paradise Lost, etc. all share some characteristics of what could be considered gothic but still I would more readily lump those bands under other genres (in the case of Paradise Lost, as far as I'm concerned they are a gothic rock band nowadays rather than a metal band). And most of the female-fronted metal bands (which nowadays seem to be the main ones receiving the "gothic metal" label) don't seem very gothic to me either. Nowadays the term seems to be applied to almost any metal band that simply chose to have clean vocals rather than growls regardless of whether their sound shares any of the characteristics of the music that made up the 80's and early 90's goth scene.
