In more details , look how a PvP player can have legendary pet AND mount with 2 really strong buffs :
- Mount Buff : after u use the mount buff, "Absorb dmg for 5sec" (seems 10secCD)
U can remove the mount and the shield still
In this video, at 2min00 u can see the buff in action (it's the yellow dome around the mage)
The mage take 10.000+ dmg (u can verify if u want) during this 5sec shield, and when the shield fade, he begins to take some damages
--> So at every engage (with mount) he has a 5sec dmg immunity
- Pet buff : after loose 7% HP in a hit, u create a buff on u for 5sec (who give u 20% Pdef / Mdef) AND if someone hit u, he takes a reflective stun for 3sec (everyone who hit)
U can see the buff on his buff icons ... it's with yellow lightning circle
When the buff proc, the same icon appear at the right side of icon buff (for 5sec ... 30secCD)
*In the same video at 2min08 u can see the buff proc and :
The ranger and mascu mage are instantly stun
Next one is the zerk at 2min10 (after his jump)
At 2min11 again the mascu mage at the right side
At 2min12 the guardian who hit the mage
5 consecutives stun on different ennemies ...
*Again in this video at 0min52 ... buff proc :
3 ennemies stun (2 ranger and 1 pala)
--> So this guy has a 5sec immunity at the engage and when he loose HP, he has during 5sec a automatic stun ennemy for 3sec
In conclusion, yes the pet/mount buffs are totally gamebreaking in PvP (open, castro, arena) and are part of the endgame stuff, as much as his armor and his weapon !!!
And following the CS that we will have, if they put items for easier pet/mount regrade (like CS in KR), it will become P2W
Atm, on JP CS u have item for change the skillpet ... so if, by chance, u obtain a legendary pet but with wrong buff, u can use ure credit card for changing their skills instead of regrade another pet
Without some 3rd buffs and the +50% backwalk, pet and mount are balanced, but some buffs are totally OP !
(for information legendary pet/mount have less than 1% chance to obtain)
