Warden Pet summoning: Summon Spirit of the Oak, Summon Oak Walker & Summon Nature Crystal: Now when player summons another pet without using Recall Pet to dismiss the current pet, the pet’s passive effects will be removed.
You know what? I'm fine with this. Wd/s shouldn't be tanking anyway. I'm under the opinion that the only reason they made the huge change to the warden class was because with heart of the oak, ANY wd/x combo could tank because they all had access to insane amounts of pdef.
Now Wd/s is a dps, and uses a dps pet. Wd/w tanks, and uses the tank pet. Sure it means nature crystal is absolutely useless now, and I won't have extra crit/crit damage while tanking, but yay, class balance!
