That's exactly why DOTA 2 is still one of the most popular online games these days especially in South East Asia regions, you can always see a lot of gamers playing DOTA 2 with different age brackets. Bringing a new patch or updates makes the game more interesting as there will be some new twist of items/skills or combo than can defy stronger heroes before the patch.
I used to play this game way back when it is just DOTA 1 until it became DOTA2 and that was when I'm still studying but now, I can only afford to watch livestreams when I have some time because I have a lot more things to do than playing.
I thought before that updates were useless and not needed but I've come to understand that it's one important feature and factor when we play.
It adds up to the strategy that we're coming up so that everyone is going to build new meta and strategies from those updates and changes that has been made.
By the way, Gamers Galaxy champ is Boom Esports.
It usually depends because most of the time they're just fixing some bugs or sometimes upgrading some graphics on the map, just some minor adjustments that needs update so that gameplay will be more smooth to the players.
But the most important ones are those who got some upgrade on skills or items, so if you didn't play just a day or two after the patch then you're more likely getting bullied in the game until you adjusted to it.
They deserved to be the champion, and they got a revenge for the Tundra for dropping them in the lower bracket.
