crossing the line in cross teaming

Just to clarify, there have been threads about cross teaming but never this specific issue

When I hop on CTF, there might be a few opposite teammates hanging around our spawn or flag room. Now I don't really mind this, until it crosses the line. A couple of times I would see chemists or mages healing opposing teammates when they are trying to capture our team's flag.

Let me put this into an example, Team B player runs to Team A's flag,
Team B reaches flag room
While another team A player is trying to kill Team B player
Team A player heals Team B player with class abilities

This situation makes it really hard to kill the other player and makes it really annoying for me and other people who feel the same

There could be multiple ways of preventing this from happening,
1. Manually punish and catch every person who does this, this could be kind of hard to do
2. Set a poison radius in the flag room, (kind of like flag poisoning) opposite team would periodically take damage if near flag room, also works as a line of defense
3. Make healing and mage heal abilities do nothing to opponents

 

Also, why do people hang out in flag rooms anyway, most of the time you could just do /team red or blue
also about "casual ctf" I get that, but people still don't want to be annoyed and want to enjoy the game how it is supposed to be played

Another issue I encountered is teammates picking up the flag and doing nothing, while the opposing team lets them be, this really pauses the game and makes it extremely annoying for us who actually want to enjoy the game how it is supposed to be played

If you want to hang out go to creative please, I find it pointless to be ruining others' experience by sabotaging the game

I get targeted alot because I play the game normally by the people that play the game abnormally
so please, if you do this, acknowledge that others like to have fun by actually PLAYING the game, rather than hanging out or some other crap
