I want to try it   

I've tried it, and it's great @Viz and for range, I think because of this Gatling it means to be farther from the range Bow and crossbow but not to over, like minigun v.10. I can shoot a monster from a very distant place (it feels too much), whereas by using Bow and crossbow the distance is not up.

Can I try Mod minigun v.9 that has not been changed. that way I can compare it with that already in change.

For damage I like it, such as the Canon weapon has the advantage of damage and burst attacks but has deficiencies in attack speed and range of attack, so for Gatling has an advantage in the speed and range of attacks and has weaknesses in less damage and attack attacks have a lag time to attack.

Thanks @Viz

I've compared Re-Mini v.9, Minigun v.10 and Old mini v.9 for attack range, I think it's better the range of attacks returns as before to a distance of 12. Sorry to bother you , my bad 

For Damage is halved I like it 

Are you going to combine Mod Re-Mini v.9, TL1 Rifles (v.4) and Spells redux (v.1) with FEP+ after this?

How about 10 meters range, so the distance is more than the distance of Canon and shorter than Bow and Crossbow.

well minigun's range is already longer than cannon 

cannon = 5 metres
wand = 6 metres
gun = 6 metres
bow = 9 metres

Okay then I just go with it   
Hmm...Why do I feel like I just joined the auction event ?
Haahaahaa... 

Nah, PJ. I decided not to merge FEP+ into Variant. 

On the other hand I still find the minigun relatively overpowered. The attack speed, combine with life steal affix is a huge life saver while cutting down potion usage.

Oh it has lifesteal? Just me, but i would remove that. It doesnt "fit" the weapon, to my mind (but again thats just me)

Idk I just found a magic minigun with life steal affix. Prob because they are pretty much regarded as cannon and cannon can roll those affix.

Will it affect Canon's weapons? (I hope not).

I've tried the latest RE Mini I experienced this, when I want to add Socket in merchant I crash. I tried using original Canon and Minigun experienced the same thing. But when you try to add skill in other merchants like fire and others and then you add Socket then there is no crash. 

I think if for "Life and Mana Steal" does not seem to be a problem, because Minigun has a time lag (colldown) in firing its weapon. It makes the weapon more stable. (that's just my opinion)

I tried to play on an elite level, and I used the voidseker / monster hunter class and also used minigun and canon for comparison.

Minigun:

When dealing with a normal level monster I can deal with it, but when it comes to monsters with an elite and championship level, you'll have difficulty fighting it (especially when you're surrounded by monsters.) And when you fight monsters that using shields, it will feel its shields so strong to be destroyed (requires a slight increase in attacks). 
I think having Life and Mana Steal when faced with the elite level will help not be easy to die.

Can spell for collingdown be like another spell? (has a level in its use). Spell collingdown is currently only split into 3 separate spells and you can get spell I in the merchant while for spell II and III you can find it in a drop monser or treasure box, but not sold in merchants. 

One more, arcane info for minigun range attack is not as it should be. Maybe still follow the info from canon weapon.

Only Minigun loses the ability to steal effect. Cannon remains unchanged.

So when i get a minigun with live and mana steal effect it will not work? but there it says live and mana steal.
Hahaha .. so funny. I understand now. 
I think there's no need to remove "Life and Mana Steal" for minigun, as I've explained before. (Just my opinion) 

Can you explain again about the crash? Do you meant that adding socketable into the minigun causing the game to crash?

When I use a monster hunter class and I just get a minigun weapon (normal) and I want to add a socket but instantly crash, then I resume the game and try the first weapon weapons (canon weapon when you play with the first class hunter class) to add socket result same. then I tried to add the skill in the merchant then I added the socket, and the crash did not happen. I then thought about deleting the save file and logs data and then I tried to get it again, now I have not crashed yet. 

Idk if I should add the other Coolant into general merchant. They are supposed to be fairly rare. I could increase the drop rate if needed.

I mean not to add coolant spell 2 & 3 to merchant, but make coolant spell like other spell which have requirement to be use (level player). thus for the use of coolant spell there is a requirement (player level). 
Would be more balanced than eliminating "live and mana to steal"
