Thoughts on investment/value?

No shit. Older things end up obsolete and new things always replace them. Only a retard would think otherwise.

This is why a lot of people say that if you are going to heavily invest in someone to ask yourself. Am I investing in this character because the meta says they are strong or is it because I like the character/playstyle? The game becomes much more enjoyable when you put your time and effort in your favourites, and there is nothing wrong with making the most out of the meta either. I play using a combination of both factors.

My +10 Roy could care less.

No amount of powercreep will ever replace my Ike.
