Sentry totems used to make shaman stop buy wow classic gold where they changed into the totem's perspective were. When I say stop I actually mean they ceased in place. If you were jumping off a hill you can fall sentry totem and float in place, click off the totem and begin falling again, click on the totem then stop set up again, over and over again. I used this at PvP largely when I had been carrying the flag in the flag area and needed an escape, or a fake.
Or in AB when I had an escape and that I jumped off the GM valley or the LM cliff. It shined in world pvp. It also came in handy in a couple of AQ40/20 fights when bosses flung you at the air and you had to cushion the fall so that you didn't die. It is not overpowered, but I feel at just how much potential it had, as though it may be overlooked a lot. It also helped deceive people when in classic wow gold battlegrounds or in world pvp.
Another one is frontstabbing rogues. You strafe forth and back and spam backstab and you're bound to land it. It did irreversible damage particularly when utilizing good weapons since it did harm based on a percentage similar to ambush.
I think too much balance hurts WoW Classic and removes the"spirit" from it. Forsaken and passing knight must have immunity to fears and charms cs they're undead lorewise. Blood elves should have higher magical dmg of taken magical dmg, and some decrease.
