Chat Bubble or floating text is definitely my choice as well.
Although I see and understand why those who prefer PvP and voice coms do not want it - as long as it is possible to turn off - why wold it matter to you?
And even though this is a full out PvP game, it is also a RP'ers dream world. And you will be surprised how many RP'ers there are that will come to this game, expecting and loving that it is a full out PvP world.
And in the end RP'ers are just as loyal to a game as Hard Core PvP'rs, and it would be silly to not impliment chat bubbles (f.e like in Lotro) to make it possible for them to "do their thing" - It would also be silly to turn that money away... *peers at Bobik*
As long as it is possible to turn it off for those who do not want it - why not, it would actually just make the game look more interesting to a wider range of people.
And in the end that means more crafters to back the PvP'ers
More players = more people for both the RP'ers and the PvP'ers to harrass, love, kill, protect, tax and so on...
