GP has always been there, it was different before, so it was trying to represent more of a usefulness number and it was failing at that. They changed it to represent an investment. Each toon now has a power that represents how much you have invested in them.
Your total GP is how much you have chosen to develop your roster, what you have available to use is about your choices.
They state the core is about investing more into a character gives you more. This is absolutely true, even now with GA, and has nothing to do with the paper zombie issue.
In their own words they are talking about wanting strategic development and strategic resource management to be a core tenant of the game and that it should always benefit the player to do so. This still holds true for GA. Some have done it more than others and are benefitting from it right now.
For those of us that have wider rosters, there will be a longer development curve, but that has always been the nature of the game. Very few are ready for a new raid or game mode when it comes out and there are always "wasted resources" that hurt our development into the "new thing". We adapt, we develop and we all try to get better.
At no point will anyone stop developing their roster and get or do better at GA, that would be against what they have stated as the "spirit of the game" issue stated with 'paper zombie'.
