i don't know who was the "genius" that put a mob that you can never kill or win xp and that bothers the players being next to you (it's a really ugly mob).
its to stop farm bots, ppl got some really good programs for that now u can only find them on some maps, not all of them u can observe ppl in KL using bots on spider spots around HG 4 or 5 and a few other places
They could increase their numbers but reduce their click box... since i dont think the programs those guys use work by clicks? So reducing the click box would prevent players from clicking so much on zombies and they still have the same effect against bots. (Only if those bots dont select mobs by clicking on them.) Even better if RF increase their number and location If bots work by click, leave them as they are and check certain parts of the maps to place them... In Phoenix spots (sometimes there are no zombies idk why), advanced base, spiders, north of lost camp in Kl... so many spots needing those beautiful zombies
