I think people are getting too "all over the place" with this discussion.
The points of the matter are the following:
"Should more US teams come over to Europe?"
and
"Would we benefit from it? And if so, in what way?"
Two of the advantages that people have been pointing out so far were the ones of it bringing more appeal to the events, being that there were famous PRO teams present and that people might attend for the sake of watching them, and the other advantage was that it would make European teams better because they'd compete against better teams/players.
As for the first advantage, whilst I do agree that people might be more persuaded to attend an event if it had all the pros that they read about in the magazines, that really would do nothing to develop the teams that Europe already has, as I guess they would be overshadowed in publicity by the more famous teams, and the Euro teams are the ones we should be looking to help, and furthermore, by having alot of guests from higher profile PRO teams, you achieve a similar effect of attracting public to see their favourite PROS up to a certain extent.
As for the idea that the European teams would only get better by bringing in American teams, I somewhat disagree, now, granted, you obviously improve alot by playing better teams on a regular basis, and the thought would be that if you brought in better teams, then the level of the league would improve and teams would get better.
That all sounds fine and dandy, but you just don't magically get better just because you got destroyed for the 3rd time by an American team, you have to want to get better, and as for the teams that are already getting destroyed in the CPL, they aren't going to suddenly want it just because the nationality of the team beating them has changed.
I've always read and heard that you get better by practicing people that are better than you, not ALOT better, or you risk getting beaten so bad that you hardly can understand what happened, but people that are slightly better than you so you get a hard practice, you have to give it your all, but it's acessible to you.
I think that what would most likely happen would be that teams would start getting smashed left and right by much better teams, and not much would change, because some of the teams in the CPL aren't better because they can't be, not everyone has the sponsorship budget or the practice conditions of Joy Division. And there isn't really much to learn in getting wiped off the field in 30 seconds, other than, "we suck".
Now I do believe that teams have alot to benefit by having players from those high profile PRO teams guest on their teams, because that way they can recieve some of their experience and learn alot more.
Also, we need to take into account the fact that it's not cost effective for American teams to come and play the Millennium Series, a good proof of that is how many XSV players you saw in Europe this season?
I'd say that the money their sponsors would shell out to fly them over would be better spent on the European teams to allow them conditions to improve.
And also, about the players liking to come over? I would say that when they used to come to Europe before, it was different, because there weren't tournaments in the US like there were in Europe, but now, I believe we are the ones lacking behind when you compare a MS event to let's say, an NPPL event...and that takes away some of the allure of coming over IMO.
