Oh my. Thanks for replying to this comment or else I wouldn't have noticed I got so downvoted. I think you guys took my comment too seriously.

I was reffering to the QUANTITY of ghost-types before gen 3; a three stage evo-line in gen 1 and a single stage in gen 2, compared to three or more ghost-type evolution lines from gen 3 onward
