I think this update was mostly negative, and not so positive, but I think there are some good idea, it just have to fix the fouls a bit.
I think it was a problem, that the old players cannot do anything with their money and token, but I don't think it's a solution to add 10 more levels, because the new players may won't stay long, because the way from the level 1 to the level 30 is very long, maybe 2 or 3 years and the old players have a big advantage in it.
May it would be a better solution to add small things, whitin they can compete, and for what they can pay money/token to each other without get too big advantage against the news and it could be may seasonable...
For it, it was a quite good idea to start an engine supplier, but I think not totally this way...
As I have written in some previous suggestion, the customers have too big advantage against the suppliers (they don't have to listen and pay, but the same result..., you can read my opinion there). I've written as a suggestion the suppliers to can break the contract, and make more details, like % of the original engine, like in real life... (They're thinking on it) and maybe to pay with token to help the developing of the suppliers...
Now I think it's possible it will be enough the two first suggestions, but I see an another problem: it isn't infinitive, it will have an end (where I think the engines will be too strong), and it goes too slow forward.
My suggestion would be to change it to a seasonable (we would have to start this only once) thing, within we could develop it in every 1-2-3... month/season and more points to develop it, but maybe in a similar way.
And for last one, I find it a really good idea to give the drivers special abilities, not to be the all the same...
But I think the 100-150 and 200 token (the old players have again a huge advantage) is very much, and in this fast world really slow to get, and it's available in the transfers for much less money. And I would do it maybe with 1 or more area, where his possible maximum number is bigger...
If i'm right, my suggestions aren't so good for the budget, but I think nobody need it to be a pay to win game... But I've never understood, why the owners don't make real contract with the sponsors and the suppliers, I think they would be open for this, because I think at the time the game has a quite big player community, so I think there would be some other option to get more money, and I could imagine even a separate league type for the players, who use real money to develop their account...
