Constant PC crash to desktop in multiplayer

I don't own the game yet but this happened all the time back in DAIMP, looks like it's the same case (CTD without any warning, no error log created either).

Also it wasn't fixed until almost one year after release, just you have the idea.

Things you can do that might lower the chance of CTDs:
- Lower graphic settings;
- Run the game in windowed mode;
- Launch the game/Origin with admin privilege;
- Add exceptions for the game .exe/folder in your antivirus software settings;
- Avoid using certain chars (I guess Human Soldier is the new Elementalist?).

Other than that there isn't much you can do I'm afraid, until BioWare address the stability issues.
