You can get 'the Boundless' and 'the Eternal' when killing or skilling on either team, but 'the Virtuous' and 'the Powerful' can only be gotten when on the Sara or Zam side respectively. Note that swapping sides, and then swapping back reduces your contribution to that side to 0.
I dislike three things about this world event. The fact that it's gather or kill for 10 weeks and hardly anything changes. The fact that it's a daily that takes a considerable amount of time. And finally the reward system with faction changing and how stuff go discontinued after. I hope those things are considered next time.
Oh and releasing it along with a new skill was a bit overwhelming in my opinion.
Hi
Yea, for like 7-8 weeks, I'd get home from work, be doing dailies for about 3 hours and only get 1-2 hours doing things that aren't limited time only..
