Because there's a difference between the player who did everything the old-fashioned way, but only had two extensions to do the old-fashioned way, and the player who arrives and has to do five of them the old-fashioned way. It's not at all the same thing in terms of perception and state of mind when you start out.Why TF should any player have to put in less effort than those who came before them?
As an aside: it would be good to stop using the 'I'm a former player' argument to excuse all the pseudo ""purist"" attitudes. If you really have a purist's attitude to the mmorpg genre, can I recommend games like Outward, Star Wars Galaxies, or T4C? These are all excellent games, and have nothing to do with FFXIV or WOW, the current mmorpg titles that are already, in themselves, the epitome of laziness if you compare them to their predecessors.
Very good! In that case, let's force all the players who've taken a big break to build a new character up to level 50. Oh, with a skill test as well, because some people are particularly slow to relearn the game. I'd also like all players below a certain dps to be excluded from my PF. Oh, and anyone who's a bit old too, they're too slow and everyone knows that boomers are unpleasant.You shouldn't be allowed to purchase a job skip until you have Lv50 in that role. I often get skippers who are completely incapable of playing their role in dutyfinder with any level of competence. Skippers are also the ones who invariably have major attitude problems, such as screaming at people for "stealing aggro" and having usual the "sit down until you kick me" tantrum when called out on their obvious inexperience.
Seriously though, that's a strange argument. You come across people who aren't very good all the time in dungeons. I don't know where you get this prejudice about skipers having a bad attitude (I've never seen it myself), but a simple reminder ("you've skipped, but learning a character can take time; you should probably do a few low-level dungeons before jumping into the content of the current expansion") is enough.
