I'm not suggesting changing characters requirements retrospectively, I agree that would be chaos! I'm suggesting (and I'm happy to concede that it might not be time just yet), that Kyro pieces should be replaced with a new piece on new characters. That way characters that are 3/4 years old aren't stuck behind the same bottleneck as the latest important characters.
CG are obviously conscious of newer player journeys hense LSB's and economy changes over the last few years etc. I'm just suggesting that this is also part of the equation. Since I started playing early 2020 (just after kyro's I believe?) we've had easily 80 characters released. The change to the game since then and the meta shift is huge. I'm not personally bogged down by kyro's, still a struggle mind. However it is healthy for the game when there is a pathway for new players to catch up.
Rock, paper, scissors comment is a little whatever, nobody is suggesting it should be easy for everyone to have everything given to them. Bottlenecks are important just need to be kept reflective of where the game is at. Relics have been released since kyro's, with R10 inevitably around the corner...
