Goldkick, it is quite hard to believe that you nundged your teammate towards the enemy by accident. According to your story, you ran to Guray with the enemies in your back, so a nudge from that direction would, even if the knockback wasnt severe, nudge him away from the enemies. Renaldo confirmed that you nudged him into his arms, which could only be achieved by deliberately walking around Guray so he would get pushed towards the enemies. EVEN IF somehow you managed to mess up your nudge so badly that it had the opposite effect of what you planned, you are perfectly aware that a nudge is giving close-by enemies the chance to score a free hit..
The fact that other people nudge you off of walls and you laugh about it doesnt make a difference as well. Some people actually want to play the game without brocoding, hugging, teamnudging/kicking and "funny" friendly kick/ban polls and similar stuff. If you do that to people and they are fine with it, ok, I have no problem with that. You should be aware though that you run the risk of sooner or later encountering somebody who does not share your sense of humour and these people then have all the right to make a complaint.
