Yeah, but that seems like it would take much longer to do than what I'm doing. You have to play the game 4 times all the way through, including the DLC, to get what you want, one for each stat. What if I want to use the Moonlight Sword? Well, I'll need a build that focus' on strength and arcane, which my skill character doesn't. That is HOURS of investment if your goal is to use that one weapon.
I want to be able to equip an weapon and just use it. And yeah, grinding to bring each stat up to 50 might take a long time, but I don't see myself as better off if I start a new game and work my way up from there. Plus I'd have to reinvest all my echoes into health and endurance, again if I did that, so there is some redundancy along the way here.
Ultimately we both are talking about the same thing: Playing the game. We both want to experience everything the game has to offer. But I don't see making a new character as an effective way to do that. I feel telling the player to play the whole game anew just so they can use other weapons is kind of awful. I also feel having this unreasonable grind to get those new weapons isn't that great either, but I find it preferable to starting the whole game over again. But really, I wish the game would just let me multiclass without being so pointlessly demanding about it. It'd need some adjustment in terms of scaling, but I don't see why the game can't just let you use anything you want.
