No . Ive been kill farming whenever i go online . Usually for about half an hour.
Its not an issue or anything because very few players have the skill requirement to killfarm , so im all for this thread.
It takes about little to no skill to start kill farming really. It only requires a minimum of 12 obsidian, and a player in the box to do a counter crit as soon as the naked person punches you (since he won't have spawn protection anymore). Pretty easy to do, to be honest.
As for the suggestion:
2v2v2v2...... wouldn't really work out well as Jollow said: There are limited colours to choose from, and a 2v2v2v.... wouldn't have enough colours available.
I'd love to see some more 5P team 40-P maps as I tend to like Teaparty. 4P team 40-P maps seems pretty doable and fun to try out, so why not!
Now: 4 teams of 10 seems honestly chaotic, but it sounds like it'd be extremely fun and it would stand out from other maps due to its nature. I would love to see these being implemented, and if I don't like it I'll just not play that one.
These map concepts seem pretty interesting, and I'd be happy to try some of them out.
