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 epic, 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
There were also some nice rewards, from my part the bag would have been enough, but the other stuff were awesome though the joy of killing that ugly spider-crab that stood over my corpse 1/4 of the whole event was worth it.
