That is rather dismissive of people who have fun with starting characters. There a many ways to have fun and people enjoy different things.
The original thing I replied to specifically spoke of someone talking about how much fun a class
would be once you reach level 7.
You are speaking of a completely different kind of person, and thus
of course I wasn't talking about that.
In my current 5e game, it took us a year of playing (somethin like 24+/- 4 hour sessions) to get to level 4 and we had a blast the whole time.
That's great for you. A lot of people--I would argue
most people--do not find such a glacially slow pace of levelling particularly fun. I, personally, have found such glacially-slow level pace to be extremely boring, nigh-infinitely frustrating, and directly causative of at least three distinct TPKs or "only one single person survived" situations. All three of which immediately led to the death of the campaign in question.
So much so that we can't imagine playing another edition of D&D really. In fact, we actually started at level 0 we like low powered play so much.
Awesome! I would never want to play at your table, but I'm glad you've found stuff you like. Personally, I would very much prefer that the game actually include "Novice Level" rules, so that you can have your nigh-infinitely-spooled-out "zero-to-slightly-more-than-zero" experience, without forcing
me to be trapped in that experience for months or
years on end. With well-crafted, front-and-center "Novice Level" rules, you could have an experience actually
designed to do what you want, for just about as long as you could possibly want (especially if it includes 13A-style "incremental advance" rules)...and nobody who
doesn't want that experience ever has to touch it. Literally a win for everyone involved except the initial design team, who would have slightly more design workload, something I'm quite okay with.
To me the lower levels are there for those you enjoy them. If you don't enjoy them you can just start at level 3 or 5, like many of the WotC adventures do.
In my experience, well over 95% of all DMs refuse to ever start at anything other than level 1. Because it's level 1. 1 is where you
start. It's the first number. That's what 1st
means. It's first. So you should always start at 1st level. Fragile characters? Nahhh, everything will be
fiiiiine, they assure me. (Oops, TPK.
Again.) Inability to address common problems? JUST BE
CLEVER, 4HEAD! Hoping to actually see some of the stronger spells or magic items or monsters or allies? No no no, you haven't
earned that yet!!! JUST WAIT ANOTHER
THREE YEARS.
I have beaten my head against this wall so many times, I've got scars on top of scars on top of scars. It never,
ever changes, and for folks like me who feel absolutely
trapped by this low-level experience and are DESPERATE to get out, it's hard to communicate exactly how infuriated I am by all this--and how much it makes me loathe playing 5e in most cases.
