With this in mind, it could be nice if they implement the old idea about a "Rise Monster" skill that let the Avenger to recall the captured monster without the need of capture it again.
The skill could have 5 mins CD and if it is still to oped, it could work only outside the battlegrounds (could be pve only skill).
The original idea comes from: Pet system changes
Rise Monster: lvl 50~71. This skill let the player summon the last captured monster. When a player capture a monster, it get registered in this skill. Once the monster is destroyed, the player can re-summon it.
-Lvl 60, hp recovery upon resurrection 50%
-Lvl 63, hp recovery upon resurrection 70%
-Lvl 66, hp recovery upon resurrection 80%
-Lvl 69, hp recovery upon resurrection 90%
-Lvl 71, hp recovery upon resurrection 100%
(edited): a little change in the % of hp, went from 20%~100% to 50%~100%. The reason is because there isnt a heal monster skill in the Hunter/ Avenger skill tree, and then the start hp shouldnt be so low.
Keep in mind that this is only an idea, and if i post it here is to let other people to improve it.
