Umm yea... the problem is your "Most People", like you, have every job at 50 with all level 90 gear when they hit HW, cause they've been playing since launch. So no they don't have a problem with it. Of course you don't even consider the new people who have no idea about the beast tribe quests, etc. Who want to experience end game content without having to grind through old, outdated content for gear that is out level in 4 levels.
You're not looking at how mind boggling stupid it is to make new level 51 gear lower Ilevel then level 50 gear. Let me spell it out for you. Craftsmanship recommended to craft a level 50 patricians item is 178. To craft a level 51 item its 468. To get the green Ilevel 70 level 50 artisan gear you need you either need to be 2nd Lieutenant in your GC which requires getting your squadron to a state where they can do the flagged mission. By which time you're near level 60 in your combat class OR you get them from Mor Dhona with HQ turn ins that require at least two or three crafting jobs high enough to get cross class skills and items needed to HQ a three star craft. This would be fine if HW was still end game... It's not. You Idea that "Most people" don't have a problem with the bump is only including people that have those jobs already leveled. Not new players who don't want to have to grind through leveling fishing to 50 just to be able to HQ a piece of armor they need. Your "I ground through it so they must be lazy if they don't want to" stems from the fact that you're looking at it through a level 70's eyes. Try this; start a new character. Give yourself absolutely no advantage from your other characters and see how "easy" the bump is. Try HQing a piece of mythrite armor with only armorer at level 50. Given the fact that you won't have money to spend on the 10k HQd mats from the marketboard because HW mats are more freaking expensive then SB mats for some reason and will have issues gathering the HQ mats yourself, with no FC or friends to help you and no cross job skills like comfort zone, steady hands 2 or innovation to help you... Yea then come back and tell me how easy the "bump" was.
So the only option new players have is to stop leveling their combat class for 2 months to grind out the crafting and the gathering jobs and get their squadron up to snuff. OR SE could have planned ahead and streamlined the gap between ARR and HW when they introduced SB........
