Also doing what you guys are talking about would force people to re-download and reinstall their whole freaking game all over again
Every patch on ru has done that. Theres been several new war2combat releases in the past 3 years alone has there not? Including one which was quickly released to remove Lambchops Chop plugin not even a month into it being part of the main combat? Warcraft 2 takes under 2 minutes to install from a fresh google search. Under a minute if you're familiar I don't know why this is one of your mains arguments against a balance patch lol, All games make you download a new patch, some of those patches alone on those games are twice the size of the full war2 game, which is like 100x war2combats size.
and on the contrary, many games force patches and have some of the largest esports. So "if you have to force it its probably trash" is a pretty silly argument. League of legends has been around longer then 10 years now, and is bigger now then it was back then. Starcraft 1, which is nearly as old as warcraft 2, is doing great. Warcraft 3, despite the mess caused by reforged, is still hosting competitive things all the time, They even adjusted the functionality of a healing spell not long ago on a hero much like what this thread is trying here, No discussion on it, it happened, and nothing drastic changed about the game after they changed that heros healing spell, no ones nostalgia was ruined because the alchemist hero is no longer also healing the enemy team with healing spray when using it on his team. it didn't make him so op that tavern heros were meta in every race. It was a balance change. It made him more usable, it made him get picked more in tournaments, if bloodlust does not get a nerf, which almost everyone doesn't deny is op, Why wouldn't you want a slight balance change for human at the very least to make them at least picked more in a matchup? If Terran has a 5% pick rate and a - 50% winrate, while protoss is 20% pickrate with a 52% winrate, and zerg is 75% pickrate with a 82% winrate, on a game that is basically the father of esports, do you not think this would be a problem in a game with such a huge competitive scene? and a forced patch to help even out those winrates would be trash? War2 is in a worse situation then that example when it comes to race pickrate and winrate.
Units / items in other games get nerfed simply for how they perform in certain maps, and thus cop a global nerf even when they dont end up on those maps. Warcraft 3 is another example of this. The Tome of experience got an experience reduction due to how it overperformed on the twisted meadows map. You could instantly go from level 1 to level 3 as a humans player immidietely after creating your hero if you got lucky with a tomb of experience drop. 1 map being too strong for it caused that change globally across all maps. they nerfed the experience on it, before only last year in 2019, they decided to finally remove the item entirely from the drop table.
