Well, i thing the question why people obviously are less interested in discussing strategys in CoH2 compared to CoH1 is an interesting one worth talking about it. I follow the CoH2 community since the very begin and i noticed the same. Please note that i don´t thing the absence of a vital strategy discussion is necessarily related with a higher amount of "XYZ is OP, please nerf" threads.
I think the absence of strategy discussions is primarily the result for of two circumstances:
1.) CoH2 offers less strategic depth compared to CoH1. I know, i know we talk about this about 1.000.000 times and not everyone will agree here. But let´s assume i am right, less strategic depth leads to less discussion about strategy.
2.) CoH2 has a smaller competitive scene then CoH1 had. Not sure about the total amount of players but you got a specific minde set if you play a game competitive. You want to win, you want to improve and you enjoy thinking about the game and the opportunities it offers. Not many CoH2 players follow this approach.
The irony is when vCoH players claim there was less whining and balance moaning back in their day and yet all they seem to spout is whining and balance moaning about CoH 2.
Well i am a CoH1 player and i don´t do that. Many others don´t do it aswell. You conclude from the eye-catching extrem situations on the rest.
People of this generation would rather complain about balance than admit they're wrong because (in general) they're extremely entitled.
You totally underestimate how many people did this in discussions about CoH1. This is not a generation problem, at least not exclusively.
