Supposed "hack" in arenas (invisibility)

Hello, I would like to report a very particular situation, an arena team accuses me of using "invisibility hack". This arena has id = 2191733 was against player named Otterpop (who is the person accusing me of using hack). I think it is strange, a few days ago a player reported me for the same "hack". I think it must be lag, I play from Chile at 254 ms. Hopefully it can be clear why this happens.

Hope you are well, greetings!

PD: I do not want to inconvenience any player or think that I am using cheats. But it's not nice to be threatened by whispers.

It happens because either you or them are using WoD models launcher, I forgot which way exactly. This causes you to be invisible to others sometimes, maybe because of certain character appearance combination?
A dude did get banned recently for a week because of this so I recommend you download (old) launcher to avoid this.

I am using the old wow client. I have never used WoD models. Because so far this has happened to me against two teams in arenas.

It has happened to me with this team with these two teams:

2072203 Noobtastic
2191733 ALPHA

send a ticket within the game, I hope it does not harm me again. Thank you very much for answering. Regards!

your enemies are the ones to use "WoD models".

Basically a side effect of using "WoD models" is that in arena your enemy might be invisible.

there is nothing you can do about that (maybe staff can finally remove client with WoD models from "download" page?)

Edit:
Next time tell them that they need to remove WoD models by doing this:
1. Open WoW folder
2. Open the Data folder.
3. Delete the patch-w.mpq file.
4. Delete the patch-x.mpq file
5. Open the enUS folder.
6. Delete the patch-enUS-w.mpq file.
7. Delete the patch-enUS-x.mpq file

Or they can download "Wotlk (old)" from warmane download page
