Ohhh pve has it trolls, arguably more than pvp. Pve players dont have any control over it, which is exactly why carrying wild dinos is off. The plantx in my base would kill whatever gets dropped in, but not the troll whos trying to burn up my fertilizer, and thats no good.
If someone put 2500+ hours into Ark and dont want the possibility of losing their work, then they made the mistake of not choosing pve 2500+ hours of gameplay ago. Its unreasonable to for these alpha tribes to think that they should be #1 forever and never lose their base/dinos.
These big tribes/alpha tribes on pvp seem to be the only ones crying about the change. Open transfers will shake up the pvp scene in a positive way for the game as a whole. There will be more rotation of power, and a better fighting chance for the lower tribes/low lvl players. The pvp game NEEDS this, badly, as servers have previously been ran by smug alphas who often times wipe everyone/anyone who could be a threat. One pvp server I had been to, the alpha didnt have that great of defenses, but would clean up the map of any efforts to build up on a regular basis. Now, they will need to build up a proper defense as they won't be able to scout EVERY map on the same basis to prevent an attack. This is a good thing, it promotes more actual pvp and situations, and promotes lesser tribes getting started by finding a safe server away from their target.
