Ahh, I know that one from somewhere...
WarCraft is the only game allowing you to modify it in so many ways. Not to mention the immense number of already created custom resources.
It is entirely your decision whether or not to completely give it up, but I can tell you this: The game is really fucking old, I haven't been playing it for more than testing and perhaps a fun game or two for years. I dislike the lore of WarCraft III and everything afterwards. However, one has to face that it still has a great modding community - even after so many years, one entire database of resources waiting to be used... That's more than you could say for other games.
But still, do as you please. If you're unhappy with the game, leave it. That's better than doing stuff again just because there is no alternate option.
