To stand out from the gray mass, you need to play not catch-up, but ahead of the curve. This obvious thesis is understood by few, and implemented by even fewer.
In fact, most Heroes players (and indeed most people in life) are more inclined to catch up and copy more advanced examples. But to surpass others, you need to use more progressive concepts that public thought hasn't yet reached.
A fresh example — I recently made scripts to change the content of preserves/hives, introduced them into tournament practice, and announced that they would be enabled by default in 1.03r. Some people immediately started testing them, researching the issue, figuring out capture options for week 1 and week 2, making balance suggestions for the content, etc. But some started negotiating with opponents to disable these scripts. The reasons are understandable (laziness, unfamiliarity, playing for fun, etc.), but later these guys will find themselves in the role of the catch-up players — the progressive part of the player base will have long since devised capture strategies and will actively use them, gaining an advantage, while these others will be learning the hard way in far more important games than now. Or they'll wait for Stinger/Alex/someone else to show and tell them how and what to do.
And the same story with TE — the most advanced part of the HeroesWorld and HeroesPortal community, if not actively playing, at least tests TE, broadening their horizons and gaining the opportunity to play against stronger opponents. It's telling that, according to estimates from bai players, the strongest play (on SoD) is demonstrated precisely by such individuals.
So, as for the Higher League, the principle is the same — you don't need to blindly copy the organizational schemes of HeroesBattle and HeroesPortal; at best, you'll end up in the role of the little brother. Better to carve out your own niche — fortunately, there are plenty of options.
