i agree with Cazasar about bad map choise. Often melee based regiments are searching for maps with hill in the middle but dont recognise the other parts of the map. This 50min round wouldn't be possible if you would saw this hill at spawn from the beginning. 12pp in our last match was mad at us when we chaigned pretty simillar map to avoid camping.
But nevertheless i played a lot off linebattles as 15thYR member and we faced a lot of campers. When Falk was leading he always tried to close up the distance without long-range shooting situations and just win in melee after a good volley. Every round after map change you could just use the same pattern as you did in 9th round.
To summarize:
It was bad map choise, and wrong tactical decision from 15thYR after side swap. No one should blame 72nd for camping for that match.
The first two rounds after map change we tried to charge them but messed up, in the third round we were trying to soften up the blow a bit but due to a few people not properly retreating back behind the hill they got shot and we were left at a disadvantage so that trying to close the space wasn't a viable option anymore and would have lead us to loose the round.
Whilst I do agree that trying to close the distance would have been preferable we actually offered the 72nd to face on levelled ground several times (even after the DC) but they (understandably) did not take the offer.
Coming to the claims that we were toxic in chat: Only 3 members wrote in Public Chat during the entire wait time whilst the 72nd members were constantly hounding us to get a reaction, now I do not want this to sound this like a condemnation, a bit of banter is justified in that situation but then going around claiming that we were the ones doing it is just not truthful.
All in all it was an unfortunate result of tactical decisions and the fact that there were no rules against it.
