Yes I believe @Alliecat7803 is quite right this does not sound like a bug. Also it's worth mentioning that battlepoints used to get reinforcements, hero's etc are not the same as your score. Dependant upon the GA you are in there are certain ways to amass battle points and this will be at a faster rate than your score. The best way tends to be not dying. If you consider people also using bounty hunter cards which at epic grants 20% increase in battle point gained, it means that if played correctly with as little as around 3-4000 score you can already exceed 6000 battle points and get a hero. For example when defending as the clones(except Kamino in this example) if you use a heavy trooper with epic bounty hunter card, you can get 6000+ battle points by firing 2 of the ion weapons at the MTT and using the entirety of your sentry on it both times without dying. Your score will not necessarily be anywhere near 6000. That is why sometimes the player in 4th for example will be able to get hero's before players above them on the scoreboard. On all GA's there is a limit of two heroes per team until the final stage where you then get 4 heroes per team. There is a cool down on the heroes in GA after they have been used I would say it is around 30 seconds but have never actually timed it as you don't really get the time to at the rate the heroes get taken during the game(the reason why sometimes they flash on and grey out very quickly).
