If you could buy 1 Epic, what would it be?

So far, I'm running on Shooter, my main arsenals: T2-T3 on Cannon (R), Sniper (R) and ExCannon (UC). T3 on Grenade (R), STorp and BTorp (UC). T3 on Std Mortar (R). I also have T2 FireBomb (R) and Napalm (R)
For Blue, I have Turbo and BShield.
I have some Epics (Missile, FireBomb, Long Range M, Ballpark M) but not using them so much, obviously they are T1.
I really want to get the Epic Railgun, I tried with the UC but it's rarely useful in battle.

Do you think it's good to spend 3000 pearls on Epic? If yes, what would it be?
Do you think it's good to have double weapons with an Epic? What would be best to double if you were me?

 

If there is a certain epic you really want to get then yes it's better to save up 3000 pearls and get it. If not the try your luck with the 3900 pearl special

 

I think it's better to buy one (if you don't get "the one" you want yet) than getting the special crate.
The special crate cost more and if you already have the Epic, you increase the chance of getting it doubled, my 2-cent
The problem is, i'm not sure on which is the one.

 

Put 900 more and get 10pack. It is random but you might get more than 1 epic, also tons of pieces and duplicate rares to improve your stuff.

 

If you don't know what you want exactly, then the epic crate is your best choice BY FAR. But still there is 35 items that you could get which leaves you at less than 3% chance of finding it. If you know exactly what you want ans you don't have an epic one of that yet, then yes, spend the money and get it BEFORE you find one randomly because.them you can't buy a second one. I never use the shop, never did. All my items that I use are already leveled up and it would take forget for me to switch them

 

If I were to get 1 epic, I would choose Fire bomb so then I could get it to tier 2
