These are no insane gamebreaking exploits, just things that I found that I thought i'd share with you guys seeing how I haven't really been active here in awhile now.
I found this awhile ago messing around with 2 manning dungeons which is a great xp booster but we all do different things. This exploit just involves 2 characters(different accounts) both within the same level range for the instance they would like to both get to.
Force Teleport your friend to your Dungeon:
Steps
#1. Complete a dungeon finder instance on Character 1.
#2. Once everyone leaves the group, kill yourself/die.
#3. Once outside the instance, leave the group(if it hasn't already left for u).
#4, Once left, go into the instance
#5. Invite your friend(Character 2) to group and if in the dungeon finder level range, he will be force teleported to the instance your in.
I just think this could lead to a lot more but I have yet to really test anything with it other than just this. (sorry cant screenshot proof because if u read post that wouldn't even be possible)
All this exploit requires is a pve realm 90 friend(or someone who is at least 1 level higher than you on a pve realm)
No Tag on PvP Realms:
Steps
#1. Get an invite from a level 90(or someone that is at least 1 level higher than you). This 90 must be from a pve(normal) realm.
#2. Both go into an instance in a neutral zone.
#3. Wait 5 minutes inside the instance with him. (you may kill stuff while waiting)
#4. Have the higher level peson or 90, log out of the game.(he may go on different toons at this time, but not the same one)
#5. Now walk outside of the instance and allow the game to phase you.(this takes up to about 15 seconds)
#6. Leave group and allow the game to phase you to your realm.
#7. gg, now you have no PvP on, on your PvP realm. (hearthstone breaks it)
This has been tested in different places but screenshots are from terrokar instance. ->Proof<-
If you are wondering i guess you could look up the Paladin if needed for proof i am/was on a PvP Server.
