The only way to keep playing NA Classic as it is, is to abandon any hope of positive change coming from NCSoft. We have to do it ourselves, and that means changing the focus from getting the ultimate +15 Archon/SW set for every character and build up the existing community.
There are still new players coming to the game, but they find themselves alone and unable to afford the gear and skills to even get to L50. Personally I like to adopt a noob whenever I can, even a little leg up can make a difference.
I just filled my 6th character slot this last weekend, and I'm bummed I can't make more because of some artificial restriction. Every time I run Ishalgen/Altgard I meet one or two new players, make sure to add them to my friends list, give them extensive advice on how to level up best and tell them to PM me with any questions.
My main is still considered a fresh 55 with TacNCO gear because I spend so much time alting, clearing campaigns for low levels and farming aether to keep those prices stable.
I've got a great Legion that does both high and low level stuff and it would be a shame to see them leave the game because so many players focus solely on end game in these insular groups of 'hardcore' players.
I'm not throwing shade at them either, we need hardcore players who know the instances like the back of their hand and are strong and rich enough to lead sieges. Those Alliance kisks aren't cheap, and when I them with only 2 players bound to it I wince a little bit, knowing my friends lists has a ton of greyed out names under L50 who wanted to join but never made it.
Chapter One has done a great job on the Asmo side recruiting and developing new players, they're my main competition when I try to recruit
Long story short, the Legion mechanic is generally under utilised. We need to share essential items via LWH, and take a little more time on running those pesky campaigns for others that still can't be soloed, even with the elite nerf.
None of that solves the manastone problem however, at least not immediately, but you really don't need a full set of green stones until 55, and what we're lacking is players who have a shot at getting there.
Just my thoughts on all this. Personally I enjoy the game as is because there's plenty to do, and if I can't get ahead at sieges I'll farm my alts or aether or level my crafts and make new friends. If I wanted a PvP game with a level playing field I'd just play a console fighting game. The challenge is what makes it fun for me.
