Please,
change these 4 things.
#1 remove a wyvern's capability to accumulate hate. after this change the wyvern would never be on any enmity list and would never be capable of drawing the monsters attention.
#2 make the wyvern immune to damage from any source.
(change #1 is to prevent abuse by using immortal wyvern to kill things)
#3 remove the wyvern healing factor from spirit link as it would not be needed anymore.
#4 find a different bonus for wyvern pdt mdt regen gear.
This change is needed due to the fact that in any real fight scenario it is unreasonable task to keep ur wyvern alive. With only 1 healing source that is slowly replenished it is not enuf to deal with the onslaught of AoE's in party situations or the massive slams of boss fight AoEs. Without our wyverns drg is a very plain DD class. Keeping it alive has become so much of a bother that many people dont even try anymore. And for those drgs who love to solo, it is becoming increasingly hard due to the flimsyness of our cohorts, as many of the new NMs have hard hitting Aga's and AoE TP moves that they use very often.
So in conclusion please consider these changes. As they would allow us to benefit from our wyvern again instead of babysitting our wyvern like we do now.
