Most valuable pet wep/type/nature?

I've searched through this whole board and I didn't find anything that answered this question, I'm currently farming a Md/Genius/Devoted for a tank pet, and I will get tons along the way, so which combinations are sought after?

 

Sly ones are really good, they can avoid most Blue AOE, iirc.

 

For me the md/genius/devoted are the best for tank but u can also get staff or knuckle instead of md but they wont be able to do long range attack. Its also depenss on how u want to build ur pet tank. If ur going to use rage attack as the main skill for holding aggro, then u should just stick with those 3 weapons. Avoid any other weapons because once u fuse and gain power, it will be harder for u to keep the magic atk higher than phy attack to make the rage atk magic based. Since those 3 wep convert all power to both atk and matk (for staff & md). For knuck it only convert half of ur pet power to matk, but its still viable to keep matk higher. Type can be phy def, genius or even skill boost to help u get a high lv skill

 

First main focus is a pet app that have magic auto. Since magic auto is always ranged, you dont have to care for weapon as long as it is md,knucks or staves. It is all ranged attack if you set it up on magic auto attack.(important for tank pet since magic autos rarely miss). Type is genius, phy def or mag def. It is a tank pet, you basically want more meaty defence. Devoted nature is a good choice since it generate aggro with auto attacks better than any nature. Sturdy is also good, more defence in general and if it have a rage attack lvl 10, it only need to land the skill once and it can dance it's way to survial while you spam them skills without much worry about aggro.
So to sum it up:
Pet app-magic auto enable
Weapon-(don't care as long as it fart magic)
Type-phy def, mag def, jeanyus
Nature-devoted(aggro),sturdy(defence)
Stat build: matk must be always be higher for rage attack to be considered magic based(thus more chances to land that skill)
Skill-rage attack(aggro, active),hp gain(more meat,passive)
