The Premium Gold Match

ARGO: I had this idea for a really cool way for players to gain some quick exp and Wargames to make some extra $$$$. Tell me what you think....
Here is the idea:
It’s like a lottery match
Each player pays 25 pieces of gold to get in this match
The match is played just like any other match except for one new addition; there is an automated “Boss Tank” which except for one spot on it is impervious to all enemy fire.
“There is a one in 5 match chance the boss tank will appear”
Players must find the weak point “which is randomly located with each appearance of the boss tank” and hit it 100 times to kill it.
Now if the boss tanks shoots, hits, or touches a player, that player’s tank will be immobile for 15 seconds “nothing on tank will work but player takes no damage”
If the tank is killed, every single player on the team that fired the killing shot receives 10,000 free exp. The player that fired the shot gets an award badge added to his credit; the losers get premium rate exp.
If the boss tank does not appear in the match, the match is played normally and all players receive premium credits and experience.
Here’s the premise:
Now players can either work together “both sides” to win or attempt to kill each other off and risk running out of ammo before killing the boss tank.
If timer runs out before boss is killed, all players receive nothing.
Idea for boss tank “World War 1 Mark V tank” Ghost of the past.
