My main rant is group finder and how this tool has killed social elements of MMORPGS and guess what you probably play MMO'S for the social aspect.
I think group finder was an excelent idea but not well executed. I think group finder should show a list of people wanting a group they should still have to ask the person on the list to party and send the invite themselves. No cross server/realm lists since it cuts out reputation for server members. No teleporting to a instance it cuts out open world environment.
When you had to look for people and talk to them to group it made a community. When it was just your server/realm players had reputations which would effect the game for them, who wants to party with a renown douche?
Lets talk PVP for a second World PVP maybe not everyones favorite part of a mmorpg but I bet alot of people would agree with me that made for some killer memories/moments. Why is it every game fails at this aspect now? because you are not forced into world pvp anymore you que in town you poof to instance. There is not even really a way to entice a conflict when that happens before you could camp a instance or a zone of high interest which would cause in the other faction or guild to fight back to achieve what they needed or just maybe to help there fledglings out so they can do what they need.
I could go on for a while but to sum it up this is why i truely believe all mmorpgs fail now. I will say I really like TSW that came out recently maybe not the best game but you know what its been a while since I had to communicate with people to get what I want rather than just do my role and zone out.
