Me and chase were discussing this, he didnt care much about green arrows, he doesnt think it warrants a ban either. I dont think the rules state it clearly enough either that using texture packs is cheating, or what specifies them as cheats, and which arent etc.
Unban i say.
Ive mentioned it a lot, but ill say it here again, if textures like these are needed, then they are fixes forced by players own hand when the game is has been ruined in some area. Ive used perma daytime before (not since a year), so now i just quit instead when night time hits. Lezard does the same and chase also despises night and says its unplayable. Yet nothing changes, and theres been threads about this. If arrows are so hard to track that they need green arrow textures, then somethings wrong. Thats atleast my opinion. Now, not a lot of things get changed in the mod anymore unfortunately, although we do get a lot of new items constantly. So people take matter into their own hands, and no rules directly state its wrong.
