Questions about Devoted pets

I caught and trained a pet (MD/Dodge/Devoted) and ended up with only 194pot VIT & 130pot AGI...
1.) Is the damage received by pet from "Cover" reduced by its resistance?
2.) Is it really necessary to have 250+pot VIT for a tank pet? (My pet uses Magic Auto with 150% atk pattern)
3.) How to fix that Dead Air animation? (Everytime my pet uses Rage Attack, she pauses for 2-3s before casting another skill or attack)
4.) Does "Play Dead" player skill affect the revive time of the pet? (because I'm tired of dying and reviving intentionally just to revive my pet fast)
5.) Are Devoted pets recommendable within a party of four players or they just serve as sacrificial lambs? (using Rage Attack, HP steal, and Cover)

 

damage from Cover and Hide is indirect. not sure if physical/magic/element resistance still apply here. probably not.

"necessary" depends on the situation. you certainly won't need that much against Boss Colon and nothing will ever be enough against Inzanio.

attack cooldown depends on the attack multiplier. the higher the number, the longer the cooldown.
aspd shortens the auto-attack interval, cspd shortens skill cooldown.

the pet dies when you die (unless it knows First Aid) and will always revive when you revive.

attack power decreases with more party members, but aggro should be unchanged.

 

I know this. I'm just hoping there's something that can reduce pets' revive time except Holy Gems.

how about ampr and aspd, do they also remain the same?

 

nope they get decreased too.
Full party reduces the pet's ampr aspd atk by around 50%
