Due to the removal of mist energy from the game the krogmo bribe function is rarely being used. I believe that since energy, which costs players money, is needed for the bribes the possible rewards should reflect this. Adding items which will always be useful to the playerbase to the pool of possible rewards would make bribing krogmo far more popular.
Here is a sample reward pool that I think would make the players feel like bribing is worth it while still retaining a net energy loss compared to energy prices at the supply depot.
35% +1 krogmo coin
25% +2 krogmo coins
18.95% +3 krogmo coins
10% Random bombhead from the current pvp bombhead pool
1% Mirrored Lockbox
.05% Random aura from a pool of auras that doesn't include the ~3 most recent promotions
The last 10% in my opinion should be different depending on if the bribe was done in lockdown or blast network to encourage play in both.
Lockdown: 9% 1 spark of life 1% 1 UV1 ticket
Blast Network: 10% 5 random fire crystals
Keep in mind that while some of the numbers seem bad the whole winning team receives the prize so it has to be balanced accordingly.
Obviously the numbers and prizes are just suggestions based on what I believe players would want while still being fair and can be worked with to find something acceptable.
The benefits of this change are the bribe function will be used more often and since the rewards are a net energy loss it would result in OOO making money instead of the function not being used. Another benefit would be possible increased activity in pvp which helps the longevity of the game. Also, I don't know how the bribe function is coded but it seems like it would be something that would be simple to implement.
In my opinion I would cut down that bombhead %.
