I disagree. Not on the sentiment of what you mean, but i disagree that "Random Luck" is the way to go. I've been in other MMO's where RL Luck played the major role in obtaining highend gear, and tbh that really really sucked.
It's not a good idea to have a system where 2 ppl putting in the exact same time/effort dont get rewarded the same.
By all means, if they wanna make it time consuming to get - do so, but make it a steady grind then, with a starting point and a visuabe endpoint.
An MMO is supposed to be fun first and formost, grinding hour after hour hoping for pure luck is not fun. I do believe that there should be some random items that could be random luck items, but not pvp endgame gear...id much rather it being vanity items such as customization options for your toon, uniqe vehicles etc.
-Just my oppinion based on alot of experience with RL luck based reward systems in another game...
