The biggie for me is when they took away my mount. Mobs hit like trucks and chase you forever. Another reason I hate Pagos is the lose xp upon death crap unless you get rezzed. This totally discouraged me from any solo play in Eureka also and I was hesitant to make long treks to join an existing group far away until I got the ports. Will I make it to my group alone without dying? Maybe, maybe not. Will they want to come all the way down wasting 10+ minutes and losing their xp and possibly a spot or impatient players just to rez me if I die? Maybe, maybe not...
The lower level chain groups are not working well. Friction between party members when another group tries to kill in the same area and I have seen griefers pull big groups of mobs on other group's players. Fates are too few and far between and a hella trek for players to get from one area on the map to the other in time to catch them. When all players finally get up there and ready to go, look forward to a sore wrist after endless repetitive motion on the mouse/keys/controler. Carpel tunnel anyone? I am almost 35 and do nothing but mash buttons for 2-3 hrs at a crack with a very occasional fate to screw up the chain.
I was hoping for more balanced, safer solo and gathering content for xp and crafting. Too few lockboxes and worthless junk for the most part. I don't like it myself but I just finished getting the relic 370 bow and mount which is nice. I met some nice people grouping, too bad I couldn't get to know them better while mashing/clicking like a madwoman during chains...
