I think the main issue for this game is that it's so fucking awesome to be apart of but it's just not getting the exposure that it deserves, everything that has gotten TF2 at this point is mainly down to a community effort and I feel that can be a really frustrating thing to be a part of.
Personally when you put so much fucking time and effort in to the game there comes a point where other things have to take a priority.
I feel that the NA scene will continue to do well, you have a better competitive scene in terms of the ESEA LANS and CEVO LANS, and as we saw at i52 you have teams that will put in a lot more effort and practice because there's so much at stake and people are always trying to be the best and less people would be willing to have a break from the game. For EU we literally only have one event, I think for EU to carry on going we need more LAN events that give people a reason to keep playing the game as most teams only really keen it up at the start of the year.
