The new front end for EQ has prevented use of EQW, the most common tool for running two instances of EQ on the same PC.
It also prevents running 2 instances of EQ reliably just in ordinary windows.
I have to wonder if this is pure accident or whether SoE have intentionally made it harder for people to run 2 instances. It is so much cheaper to have 2 instances running than a whole separate PC rig that I'm sure that it was a very common thing.
However it does encourage a certain insularity. I found it much easier to duo two of my characters rather than find a group. With two characters you can do an awful lot that you can't do with one. I was developing an entire playstyle around a set of duos.
Now I will have to either solo or group again. SoE have repeatedly said that they wish to promote grouping. I wonder if they have acted intentionally to change this dynamic.
Probably I'm just paranoid and it is another example of god-awful programming.
