First, I have a question to the admins and depending on the answer I have a suggestion for the XP points and ranking system.
I understand that XP is given out depending on your results in relation to how your opponents are ranked.
Does a 25%, a 50% and a 100% race give the same amount of XP?
If so, I suggest that 50% races give managers 50% XP as they would have received if it had been a 100% league. You learn a lot more in a 100% race (I would guess about 100% more actually) than in a 50% race.
Also necessary is to remove tiers for leagues that doesn't want them. If a league only wants one division (like in real F1), then they shouldn't be forced to run as rookies with level 8 cap on everyone.
Cheers,
