title says it all. I've never tried, but it seems like it could help. Obviously, this could be exploited with backstabs on allied FFAs. but, in team armies it should be a thing.
Yeah, but you can mess with their teleports, stop them from getting stuff to the right place- It could just be a mess. So, really, only with permanent alliances. Also, you'd have to look at all of your allies bases and secret teleport things they set up just to screw with you to find which one is disrupting your network.
The point is that people play non shared so other people can't mess with their units, if they on the other hand can mess with your teleporters, that would be a problem. (But I often miss the option to link a tele with a non share ally, too)
Yeah, I agree sometimes connecting teleporters to non share allies would be really welcome especially when that ally is very near to be overrun.
To avoid abuse the teleporters should only link once you and your ally/teammate both give the link command to the other guys teleporter. I really really want this, but having control over another team's units is problematic programming wise I believe.
