Found the post with my idea:

Here's an idea.

'Random encounter' world bosses. What would happen is before a world boss spawns in a particular area, their coming is announced by an announcer in all 3 cities. Then any parties that want to take part sign up to it on some kind of task board. They must then travel to the area the world boss was reported to be in and battle it. All parties will take part in it's battle as if one giant party, it could consist of up to 100 or even more people, no real limit, and the difficulty and health of the boss would scale to how many players it had to battle. However a minimum player size would probably be an idea since soloing it would be silly.
Once defeated the boss would give each party a random part of a legendary item. The overall size of the battle party from how many players were involved overall could even dictate if a HQ version of an item part is obtained. The party would have take part in many of these 'random encounter world boss' events that would happen say.... 2 or 3 times a day, maybe 5 times, and get all parts to the legendary item, the bosses would differ in what it was and where it appeared in the world, thus 'random encounter'.
They are then notified when all parts of the legendary item have been obtained by a quest being given to them automatically upon aquiring the final item.
This quest would entail them going to a special dungeon that you could not enter without a completed set of legendary item parts, and once completed, would allow the player with all the items to forge the completed legendary item and wield it.

This would mean that getting a legendary item would take quite a while and be pretty difficult.

Getting a High Quality legendary item would be EXTREMELY hard to obtain, as you'd need to have taken part in very large scale world boss encounters multiple times and had the luck to obtain a full set of the HQ parts to the legendary item. It would also be nice if that high quality version had something slightly different about it's appearance that marked it as 'the legendary of legendary' items. (something like an awesome glow etc.)

This way casual gamers would be able to get legendary items if they spent enough time working towards it, it would still take months though.

Hardcore gamers could get the awesome legendary items though, so both types of players would not be ignored for their dedication to the game.

What do you think? ^.^

I'd also say this is on topic as it's a suggestion as to the possibility that would take 3 months just to obtain, therefore filling the gap the other gear could possibly cause. :3
