Most living in Bosnia along the Croatian border in the south-west are already ethnic Croatians, and they cross the border unimpeded to Croatia for all its benefits. Those that are not ethnic Croatians are likely ethnic Bosnian there, who cross as unimpeded as well, except they likely give less shit about it because they are just visiting their relatives or enjoying their EUR-bought or built homes during the summer but then go back to Germany to work for the rest of the year.
Now here's another funky bit. Sometimes taking a break from a game and coming back to it weeks, months or even years later will make it feel like you've never been better before. And the numbers or scores might validate it.
I've personally experienced this with:
QuakeWorld in the early 2000s, where my shaft hitscan rate went from low 20s to mid 30s and my movement control got even more fluid. Factor here might have been a PC upgrade
WoW around 2008 -> 2010 where I went from struggling in arena to hit the lowest rank to duelist. Factor here might have been my aging reflexes starting to compensate more strategy instead
Enter the Gungeon from 2013 -> 2015 where I was struggling to get past the first few biomes to maxing out the whole game and attempting streaks with 9 curse and turbo on. This definitely came after watching a few streamers trying to do speed runs and their movement and situational awareness of the mob patterns inspired me.
I've also revisited these games since, again, and definitely only gotten worse at them.
My match making in Quakeworld late nineties / early two thousands went from LAN with dad and brother at home, to LAN at compsci lab at HS after school, to local PC cafe, to regional LAN tournament to international scene once ISDN & ADSL became ubiquitous.
We were always welcoming newbies to the scene. But then starting 2003 the Nordic players became increasingly cliquey and started refusing to play anywhere further south than servers located near the Stockholm datacentre.
