Alright here it goes for the disbelievers. I asked Forsaken to come be my guinea pig for a quick video, knowing full well this wouldn't end well for him. Forsaken is a good mage, and a known pvper. You'll notice here he even apples to remove curse causing the Phoenix to do less damage. It really doesn't matter because the second it dismounts him he is done for, which is why i casually casted a few spells. This could of been over faster with a real combo, but i really wanted to see the dismount get off. Unfortunately Forsaken is a good dude, and actually tried to cast some offense at the beginning rather than just flat out running away, so the phoenix speed didn't show off, but we'll get to that.
You'll also notice that when it dismounts him, I remain on mount. Very imbalanced. You pretty much stick it on someone and play defensively until the dismount goes off, then go full offense. He tries to move away and heal once he is dismounted, but there is no running from it while also trying to heal to recover.
Should I also mention that Forsaken is a wrestle/parry mage? He is on a DEFENSIVE template against melee, and it barely helped him.
To give further example of that, here is me sticking the phoenix on me. I am not cursed so the damages are a bit less. My phoenix also isn't max damage, and still has magery. Several people are using mystic so the phoenix can sleep for itself, and spellweaving so the phoenix casts wind/thunderstorm. These cause much greater problems.
You'll notice here, that I can run with it, not from it. It has 120 resist, so I cannot paralyze it, and though it at times appear to be a few tiles behind, the 19 damage ticks are it's melee damage on me uncursed meaning it is still hitting me because of the speed. It quickly jumps back to right on me though. Also take notice, that as soon as I attempt to cast a spell, which pauses you, i'm done in. Now imagine that, but with a mage casting you down mounted, or a dexer nerve striking, AI, deathstrike, etc..
Now I feel i've done my due dilligence in trying to get these pets addressed. I've done more testing on test center than most people pre and post publish and feel I am in a good position to explain these things. Balls in your court before pvp is totally diminished from these pets, which is unfortunate because pvp has been EXTREMELY active, and now the pets are going to knock it wayyy back.
