I kind of understand why some people are frustrated and against this move by Linköping, but I personally believe there's nothing wrong here - at least from Linköping's part. As a matter of fact, this will most likely be a great thing for the eSHL as a whole.
If there's something that should've been done differently for the upcoming eSHL, it'd be for eSHL teams to have some kind of common ground and criteria or guideline for their teams and how they should be built. As of right now, I see some teams building their rosters purely out of locals and/or having all kinds of players coming in through internet applications and local tryouts. I'm not saying recruiting bunch of Finns (or players of other nationalities) is what these teams should look out for, but I think it's must worse to have eSHL team(s) built out of some beer night tryouts than recruiting an actual team (or have a person who knows the scene build the team). These teams have a huge risk of turning out just like so many FCL, SCL and IS Cup teams that join into the tournament after reading about it on paper, get trashed and maybe even quit mid-way through. And bare in mind, these teams that might get absolutely trashed will be representing an actual hockey organization. They're not like some random group of friends who can leave the tournament after losing 8 games by 10 goals each.
Congrats to Linköping/FILA for the signing!
