The problem with your argument is you are making too many assumptions and leave to many things unclear.
1. TOP and Co. attacked CnG. Not the other way around. (This is fact and everyone can agree on this)
2. I have fought at least 4 TOP members and at least 3 of them had warchest above 1 billion. and you can't tell me those were exceptions. (Irrelevant and your making assumptions that the majority are like this)
3. Think about what TOP would do if they would win. yes indeed ask for reps. (Another assumption and the fact that they have asked for reps in the past may increas the likely hood but does not dictate that there will be reps, that is flawed argument)
4. Another reason why they are getting such high reps: there are a lot of Alliance's involved. TOP well done, only you have lost and everybody wants a bit of you. (Only aggressive action was against CnG, the fact that others joined in to help them makes them good allies and should be supported by those they helped, the fact that they stood in the crossfire is their own issue not Top and Companies.)
5. there has never been so much money on planet bob. a average nation now has at least 150m where that was 50m 2 years ago. (Again, irrelevant. Its a game and as such the prices have a set value, its not RL where market values rise and fall, to ask for more simply because you can is nonsense)
6. know the risk of attacking. if you gamble big, prepare to lose big. (These alliances don't make 'gambles' like this, they felt their support of their allies would result in a direct attack from CnG so preemptively attacked to better secure the future for their allies, while this obviously failed I would hardly call it a 'gamble')
