Mana buffer (80% or 90% or something) for arena events to account for upkeep. It gets a bit silly and aggravating when people start spamming drink mana|challenge x|accept x while just barely missing the window of both being 100%.
E- Was specifically thinking of spars. Events would need more thought, since it's a global teleport
And, because I am such a classical music fan, I'm offering 10 credits to the first person who can identify all 5 J.S. Bach pieces sampled in the above video.
Most people doing cairns were either alts of existing players or folks drug here by existing players. Getting aspect quickly doesn't break RP potential. At all. Also plenty of MMO's have some system to let you start a high level character so you can dive into pvp quickly. I know WOW has. I know LOTRO and DDO have. It makes good sense or the players and for the business.
EDIT: I made 2 newbs to see how long it would take to achieve aspect. It was roughly 2 hours of effort on each. I also spent most of the cairnae raising my numerous alts to aspect. It was effort, but it was also the only way I'd ever do aspect again. The reward is honestly not worth the investment of time and energy normally. Now, though, those characters have a much better range of skills. Which makes them far more enjoyable to play. Which makes it more likely I will pick up the stories I have built around them at various points in the last decade.
