It wasn't so hard in the old days.... GB's and Guilds were out before the first Xmas... Hoods were static and no-one was using goods for anything but research (no GvG or GE to suck goods out of the game) so it certainly wasn't difficult to acquire them... there were only a few era's, Attack GB's gave 50%, Infiltrate cost only a few pennies no matter what era you were in.... it was such a simple, kids game at that time that it was advertised on Nickelodeon or some similar channel, which is where I first saw it with my 9 year old.... to pretend it was so difficult requires a very selective memory...
No-one is saying they can't progress without FP packs... just that they prefered the FP's as packs.... and newer players win a very low value amount of packs from GB's and one consequence of this change is that it does give an (even greater) advantage to high level Arc Players over them...
BTW... I'm not attacking or demeaning the achievements of any older players... anyone with an advanced city has nothing but my respect as I know how much time and effort it takes to acquire it... it's just that I'm wary about this particular change as there really was no need for it unless the end game was to move all FP's to the bar... and bye bye GB and quest FP packs... and that I really wouldn't like....
