Genies are a little bit useless?

Now my genie is lvl 60 and i see that it's skills are a little bit usless.

Maybe i'm wrong, but idk.

I've holly path... yep, this is a little usefull in some cases, like dungeons, etc.
and now Reflective aura... its useless. the effect just takes 3 seconds, this is too little... it would be usefull if it takes 30 seconds, but 3?

What i dont get about reflective aura, is that it says:
"Up to a Maximum of 10.000 damage will be reflected."
and this number increases 10.000 every level. OK, if it can only reflect one attack, which it hits me about 200-300, why do i need to increase that number? there's no sense. It'd have more sense if every lvl increases the duration.

OH OK, Right, every 40 DEX points increase duration by 1 sec. BUT EVERY 40.
at lvl 100, with 100/100 lucky points, if u put ALL the atr points into DEX, duration will be increased by 5 seconds. this is ridicolous. How much EXP and SP do u need to get a lvl 100 with 100 lucky points? is it worth to get the duration up to 8? you'll reflect 2 or 3 skills, no more.

Genies were made to help, not to spend a lot of SP and EXP to get a skill it won't help you.
