does the gateway have a combat exit still? i remember reading about the heads exit being removed, but potentially it can be replaced with a series of progression fights aimed to challenge new players. perhaps we shift the basic creatures (barren and grasan) , to the island as well, and set small challenges, nothing major, just basic combat ideas. this would allow them to dip their toes into thinking about combat, provide a solo way off the island, but also allow returning vets to steam through it and leave if that's what they want. upon beating the challenges an item could be granted that allows a one time exit, so it's not forced, so that if they win they have an out but can choose to stay if there are other things they want to see.
also i think allowing people back and forth with "ease" wouldn't be a terrible idea. and everything that's set to focus on newer players that vets shouldn't be using can be hidden based on AD , i understand that parts of gwi are meant to be a reward for vets finding their way there but is that the best idea? i can't say for certain, i can see for and against. but it would alos allow newer players to leave and not feel punished for not finding everything (especially in conjuction with my next idea)
another thing that people like are spells, perhaps some new very weak spells could be introduced that can be gained on the island? and a quest could be introduced to unlock the visability of the erohlin at mp3, because we all know it's still there and working even at that level, but unlocking it would add an extra bit of content and introduce them to what it does, how it works, and spellcasting
