there arent really pest control worlds, as clans nd teams move when they get too crowded and games get slow. however there are ones that they favour. one of them is 100 nd another is 31. Not too sure bout w78. i guess because it can get full at peak times at will have a good number of people at pc, but wouldnt really call it a 'pc world' i disagree with w2 bein duelin wrld. w2 is merchantin wrld. maybe w6 or 18, as both are busy with good pk in wildy. not too sure on duelin arena. well, thats what i think. maybe do a little research? i cant be botherd to do some though
