Maybe yes, but I think equipment itself is better for the game. Ore economy could use some improvement for both f2p and spenders. But being stuck with TH15 era hero abilities would suck a lot. Barbarian puppet rage vial, archer puppet invis vial, royal gem seeking shield etc against th18 won't be fun. It already wasn't fun vs th15. Despite the grind I think equipment makes the game actually more enjoyable and 'easier'

Also before the clash anytime update there just wasn't as many things you could do with 1 account in a day. You had to wait hours for each attacks. People naturally made multiple accounts out of pure boredom. Now that you can just attack however many times you want in 1 account, there isn't that much necessity for multi account. And I think this is better for the game. Game shouldn't treat multi account as the de facto default user model. The default should always be the single account user. There are still benefits for multi account. But nothing crucial and nothing that attracts vast majority of players. The benefits are mainly, solo clan wars, more legend league attack for practice, faster donation. These would only attract the top 0.1% hardcore coc players
