rewards for success

Winning championships although great for personal achievement and bragging rights should also come with financial rewards for the team .
Mirroring real F1 prize money should be awarded at the end of the season to teams based on there finishing positions .
Maybe something could also be done with sponsors to reflect the team's achievers too .
I know the game is based around new teams being able to catch up but existing teams have much higher costs and should somehow be compensated  for their loyalty.

Loyalty......
Compensation.....
Revenue......
Freebies....

Anyway you put it....these are phrases that are simply difficult to be talked about in the same sentence. All good thoughts Mr. Nightmare... but it will be a cold day in hell before any of that happens here. 

Having said all that.... the devs do a reasonable job at making sure this isn't another pay-to-win app. 

I get your point and I agree. There should be something other than the regular sponsorship revenue. Or maybe that's the point...to make us spend our coins the further we get into the game.... hmmm.... how tricky.... never seen that anywhere else...    HA!

It's not even necessary to be huge amounts of money. Even if it's just 2m, 1m, 0.5m for the top 3 places would be sufficient
