It is great to have events and on such a young map. Keeps thing exciting and challenging. Some people thought the way you do now when the fear Evolved was coming last year. Oh-no, my base will be gone. Oh-No, I will lose everything. This is not an extinction event. So calm down.
I think the dodoRex and DodoWyvern are cool and I do not live in a thatch hut or troll servers. The statement of "Only Players" and "Majority of players" carries no weight, especially when making a personal opinion. I play on an unofficial server with only minor changes to default (nothing big at all - still need to grind and wait on long tames, etc). I am preparing now to take the fight to these creatures. Will I lose tames? Yes, but that is part of the game. I am looking forward to this event.
If you are fed up or disagree to how the game is going as well as make threats of leaving (including deciding for your friends to leave), then now would be a good time to load up your dinos and go bye bye. But you won't leave. In the extremely rare chance that you would leave, you will be back. I don't care either way.
I seen players complain last year before events (all events) but then after the events, hmmm, attitudes changed. Guess they realized that they were actually fun and different.
Have a great day.
