Many of you are aware that damage indicators is an approved mod on this server, but most servers don't allow it. We know that it allows a user to see enemy health, which isn't a vanilla mechanic. Here's why it shouldn't be allowed, aside from just showing health. -It's an unfair advantage. I've posted this on the updated rules thread, but I'll say it here again: knowing enemy health gives a HUGE advantage in PvP-based minigames. This allows the user to know when to engage enemies and when to back away. Example 1: Suppose Player A has the mod installed but Player B does not. Player A sees Player B with 1 HP and decides to rush Player B. Player B, however, does not know Player A's health. Example 2, reusing Player A and B from first example: Player A has taken a bit of damage and sees Player B with full HP. Player A can then tactically decide to retreat and wait for Player B to attack. Put from Player B's perspective, he has to assume Player A has full HP. -It shows potion effects. Suppose a player has multiple potion effects. Potion particles would show a mixed color, but with that installed, one can see all the effects a player has, further determining whether to engage the opponent or not. -It is also a hack in most hacked clients such as Wurst. This hack is known as healthtags, which does the same thing: shows enemy player health. It's ironic that hacked clients aren't allowed, yet this mod is. So, is it fine then to have a cheater use a hacked client with health tags only? From my post on the updated rules thread: The only vanilla way to know how much HP a player has is to assume he/she has full HP and then note how much damage the target received. Even then, that calculation does not always work, as the target could have extra HP (gapples), enchants, or could have taken damage before the fight. TL;DR: It's a hack. Leave your feedback below.
