That's all excuses. People and authorities in Zagreb just do not care about hockey. Believe me, if Galatasaray or Fenerbahce iced a KHL team today, even the game against Amur would be sold-out, and we are talking about a country which literally has no idea what ice hockey even is. If KHL is not saving Medvescak, EBEL will not either. The problem seems to be lying much deeper. If the team returns to EBEL, which doesn't seem to be the case, maybe it will look more successful and the attendance figures will get better but that's all. In the long run, Medvescak will grab nothing worth mentioning yet again.
If you do not invest in infrastructure and make new ice rinks, get local kids to ice while you have a KHL team, then you wil definitely not be able to do this with EBEL either. As I said, obviously, people in Zagreb just do not love hockey as much as we assume they do.
Medvescak is not like Barcelona yet when they are a team from KHL, their recognition internationally is also much better. kabidjan18 may again blame me for catering to myself, but Medvescak is my little brother's favorite team in KHL for example and he even saves money to see them in future if possible. In EBEL,you won't have 12 year-old fans like that who sing "Zig zag Medvescak!" all the day. Now you may say, "LOL, what does it have to do with the team? Why 12 year-old children would matter for Medvescak?" and you are partly right. But that's recognition and marketing dude. My brother is not the only person who got to know Medvescak. Thanks to KHL, many many people learnt about the team and some even grew sympathy for them, like my little dude. In EBEL, your reach area is much narrower. And don't forget these fans are much more eager to buy your products compared to their Croatian counterparts. Having a Medvescak product like a scarf or hockey jersey in Turkey is very cool. In Croatia, it's just normal. So, while local fans are the main source of interest and income for the team, foreigners also have to be taken into account. Because, for god's sake, you are KHL team. You may have Finnish, Swedish, Russian, Latvian etc. fans!
Anyway. As I said, under normal circumstances, being part of the second best league would generate profits for youin any way possible. On ice, financially, merchandising-wise etc; simply because you are "famous" now. As Alessandro said, this does not really need explanation: being in the league alone has benefits yet you need to reap them. Medvescak just doesn't have these tools.
Are there any news now? If I am not mistaken, the deadline for registration in KHL is April 1, though I am not sure if Medvescak has to re-join the league as they are already part of it. Let's keep your fingers crossed for the best. Who knows, maybe next few years will bring huge improvements to Zagreb and we'll see a competitive, CSKA-punching Medvescak soon.
