Alting is always necessary. It just depends on how serious you are. In BDO people had their alt chars stashed at world boss spots so they could log in and farm lol. It's always going to be necessary because it's always going to give an advantage, or a diff build, that's why most games don't have just 1 slot.
It's not 'necessary' in MO fr fr, but you gotta be patient. None of us are. Most of us would rather just be able to do what needs to be done. It's like tryin' to score somethin' at 2am callin people's straight to voice mail celphones.
I heavily resist the suggestion of reducing prof points, the problem is that certain builds require a certain amount of primary points. Even as far as to be 'human.' They did all this weird shit like reducing 70 crafts, etc etc, they took away most of the benefit for 100 when 98 in MO1 was some "I'm not buying that shit." MO was alt heavy but at least you could trade between accts and you had multi chars. Don't you guys like to be different people, diff builds?
It is true however that their sell acct model probably saved their project from immediately going under cuz of lack of sub, so... haha. Mysterious ways.
Edit: I know you Mo1 kids know, but people actually had free to play mining alts, some set up on bots. Ask stril about how to work that shit out haha. It can become nonsense p quick. That's one cool thing about a sub. That's the idea. So I mean FIX THE PROBLEMS (tbh I'd like to be able to respec my char into archetypes or at least quickread up some stuff. Like save your build into something and read that build book for 24h and you are that.
