This be my suggestion.
Values are changeable.
Normal Coin Gain:Sector Coins: 1 per 10 exp
Indiv. Pvp Coins: 10 per 1 exp
Team Pvp Coins: 5 per 1 exp
Bvb Coins: 15 per 1 exp
Effective Bonuses:Sector-Time Bonus [eg. I finish a level within 30 seconds after time limit + (Insert a value here) multiplier]
-Hitting Avg. Bonus [eg. Out of 30 atks I hit 30 times = A+ = (Value) multiplier]
-Health Left [eg. I have 1000 hp. I finish a lv with 500 exp. I get (Value) multiplier]
-Team Members Alive [eg. I am sectoring with a pal. He dies. I only get (Value) multiplier]
Pvp-Indiv. Pvp -Win Bonus [eg. I win a game. I get a bonus (Value) multiplier for coins]
-Player Kill [eg. I kill 2/3 players. I get (Value) multiplier]
-Seconds Alive [eg. I last throughout a game of 5:30 minutes. I get 5 coins and 3000 gigas]
-Team Pvp -Team Win Bonus [eg. My team wins a game. We each get (Value) multiplier]
-Team Contribution [eg. My team killed 4 people total. I killed 4. I get a bonus (Value) multiplier]
-Team Balance [eg. My team has 2 less people. We each get (Value) multiplier]
(Bvb is same as Pvp, with an exception for "Seconds Alive". It is to be replaced with "Lives Left". And kill bonuses do not count for mob kills.)
ExtrasWhen you kill someone, extra coins will drop from their body, in a manner similiar to the way BotStract does.In Indiv. Pvp, you have 5 seconds to grab before they become free-for-all. In Team Pvp you have 3 seconds to grab them before your teammates can. After 5 seconds, you and your teammates can all grab the coins. After 10 seconds, the coins are free-for-all. BotStract will also drop, BotStract can be used in-game as a minor speed and damage boost, just press the shortcut for it. Press the numbers 1-0 (0 = 10 'Stract btw) for the corresponding amount of 'Stracts. 1 'Stract = 1 extra Atk, 1 extra Speed, and 1 extra TG, etc, however the GMs wanna put it. The amount you use will last throughout the game, until you die, this counts for sector too. You can set an "Auto Stractor" to automatically set the amount of used 'Stracts before the game starts. BotStract can be exchanged for coins and gigas, the exchange amount depending on how the GMs want it worked out. Coins and gigas can also be exchanged into 'Stract. These can be exchanged via either set exchange rate or live market, up to the GMs. And finally, II Skills will be dropped from Lv X, they will last 100 games, and they are uncommon and randomly-chosen, so that people won't abuse it. (Or they can just buy it for a VERY VERY VERY expensive price. 20 games only pl0x)
This be the end of my very long suggestion.
I will buy you a taco if you read all of it.
