Simple question, with a poll. I think it was buggy as hell and if they make these one time events they should first check that they're not bugged in key parts. If it was an event available for more time, sure, the bug would get fixed once, but like this... bugs kind of stopped you from going forward with the chain, had problems in P2 because of disappearing kraka and being one of the last servers to actually get to fight etc. I don't know, I found it a bit disappointing.
Even if there's another phase tomorrow, after both previous phases were bugged... I don't think this last one will be any better.
As I said before, ArenaNet are good at many things... but not these one time events.
We're only talking about event here, the island is ok, went there, I like how it looks. Since I'm not 80 for good, the mobs are too hard for me so didn't sit long, but that's another thing.
Edit: Ok, just did the last part. I'm glad to say I was wrong. The third part was great. I really liked it. It felt ok, had some nice rewards, no lag, and the only thing I disliked about it was that there could have been 1 less reinforcements part (so from 2 to 1) but besides that it was great
