lets do the math
green packs
max training facility: 7 packs every 4 days = 49 per season
gifts: 1 per day = 28 per season
league: 26 matches = 26 per season
cup: 13 matches = 13 per season
champions: 13 matches = 13 per season
total: 129 per season
red packs
max medical facility: 7 packs every 4 days = 49 per season
gifts: 1 per day = 28 per season
league: 26 matches = 26 per season
cup: 13 matches = 13 per season
champions: 13 matches = 13 per season
total: 129 per season
blue packs
gifts: 1 per day = 28 per season
league: 26 matches watched, won and dominated = 78 per season
cup: 13 matches watched, won and dominated = 39 per season
champions: 13 matches, won and dominated = 39 per season
total: 184 per season
But all totals are maximums. You will get less because:
very rare to play all 52 games in a season
impossible to go through a season without a card
very rare to win all 52 games
probably impossible to dominate all 52 games
but you can
watch every match you play
make a substitution every match
build your facilities to max
get and receive gifts
So, a "normal" player (about half way through cup, no champions league) is going to get:
around 110 greens
around 95 reds
around 80 blues
add a few packs to each total if you do make the champions league. Also, above numbers take into account max facilities, which you get about 10 to 11 months after starting to play the game (no tokens spent to speed up facilities).
So, yes, videos for the bonus packs are needed, especially the green ones for those of us who power train. Power training means a player can stay on the squad longer. Player staying on the squad longer means I don't have to spend tokens for a new player.
