I understand what you’re saying but I don’t see why this forces me to change how I’m going to play (much). Yeah, if you play one class for a while and then decide on a different main, it takes more time and money to get to the endgame. But if that means I don’t get to do a lot of T3 content for 3 months versus one, why would it matter to me? I don’t feel compelled to rush to the endgame, and I’ll get there eventually. So if I play for a while and don’t enjoy what I’m doing, I’m going to switch to something else that seems like it’ll be more enjoyable.
Also, from what I have read, once they put catch-up mechanics in the game after a while so people who are switching mains have a way to bring their alt up to speed.
To me the bottom line is whether I’m enjoying my time in the game.
