If Gamefreak suddenly said "Y'know what, screw it!" and wiped the dex/truly rebooted the series, and made the pokes more balanced, and there was no IV's...you guys would have a hard time picking w/ a choice between 200, let alone 700 :/
A. Not everyone likes every Pokemon. I'm not sure I even like 6 fully evolved Pokemon in the gen. More Pokemon means a better chance to satisfy everyone. B. I have definitely used the majority of Pokemon to some degree.
Using a fixed amount and having an expansive selection to choose from are two entirely different things.
Yet, on one hand, most of them you will ignore even if there were 200 of them. Secondly, you still wouldn't primarily choose over 10 of them.
TC's logic stands firm.
Yes I may choose ten and ignore the rest. But someone else may choose ten different ones and ignore the rest and so on. What appeals to some doesn't necessarily appeal to all. Especially with a vast online community.
