Its not even about the money, well it is to an extent. As you said its negligible the amount of money won buts its still an incentive. The main thing is there just isnt any competition for teams to get to that next level in terms of skill and to actually have the drive to push themselves to the next level.
No team in Europe, since full tilt, have posed such a threat to Se7en for them to actively go over stuff and be keen to fix their mistakes. Full tilt was a team that could take coudl regularly take maps off Se7en/Crowns. Yeah I know arctic foxes beat them in the grand finals that time but it was a Se7en who had no drive or anything they literally showed up to officials and that was it.
I'm not making excuses up for them losing to them, I can see why Se7en didnt practice that season and yeah it fucked them over but as I said it was a team which had no drive as there was no actual rivals for them to deem it necessary for them to be keen.
Around the time of last rewind, in my opinion was the last time Se7en gave a shit. i61 was going to be another time you would see an eu team be really fucking keen and strong but Froyo decided the smartest decision was to not attend.
Now the next rewind is soon, Froyo are attending and so is Se7en and guess what? Se7en are actually playing and preparing themselves for this as there is actually going to be some competition for them.
In the past things just seemed so much more organised, more keen and there was more drive to improve.
I know I've just used Se7en as an example but its the only team in europe thats been able to stick together and continuously improve.
