I understand the main "father" of the current rules - esteemed invisible - in his struggle against innovations.

First of all, I'm not a "father," but I'm planning to become one soon :D, and I didn't write the rules - I, vbn, and a few other players just tweaked the Portal rules!
Secondly, I'm not a conservative; I'm always in favor of "new and promising" things. I'm just saying this in advance so you don't get offended. How many online games have you played? Judging by the reports, not more than ten. And you, with virtually no online gaming experience, are starting to introduce things that players with hundreds of games under their belts view from a slightly different perspective. For example, the ban on the +6 helmet. Why not a +5 sword? So, +6 is a cheat, but +5 or +4 isn't? This is just an example, and I don't want to discuss it. Some people are constantly complaining: either their opponent has an explosion, or the respawn is weak, or there are blocks, or some other nonsense. If playing Heroes with these rules is such a lottery, then tell me: why do players like Pit, LeBron, Paladin, Forrest, Vic, etc., win so often?! Is it just luck that they always get good draws?! Pit has a ton of medals, both on HotA and on Horn of the Abyss. Why doesn't he complain that his opponent got a Utopia with teapots, pots, and other junk? Why does he win most of the time? Why can you only win against Forrest when he's hungover? (just kidding, he doesn't drink :)))) Maybe the reason for "unlucky draws" and imbalances lies somewhere else? Pit was right: you don't need to change the rules to suit yourself; you need to improve your skills to play them well.
Sorry again for the rudeness :).
