Battleground banks and payout
I have a few of questions about battlegrounds, any tips would be much appreciated!
1- What is the best way to fill up the BG bank? Is it by sacrificing units to the highest mission BG's without beating it? does beating lower BG's not fill up the bank properly?
2- What is the best BG to get your pay out at, is it the highest mission or the BG right after it. Is getting payouts in mid level BG's bad?
3- Last and not least! How to determine if I got the full payout, and is there a way to trigger a full payout?
Thanks a lot guys!
