Need build assistance from master1 to ace3 players

So, I run an epic t2 standard shield, t4 rare big shield, t4 rare turbo. (Both the rare blue items at lvl 36ish).

Which one should I upgrade first? The turbo or the big shield?.

 

Btw, I'm play long range shooter style, dual sniper, dual long range mortar and one standard mortar.

 

Got it, I'm nearly close to the 1.5 limit anyways, I'm at 1.42 rn.

Secondly,
All my items are rares and epics (t5 rare sniper and lrm, epic 4 lrm and stm and one t3 sniper)

Got the extra parts to make a t4 epic sniper and will soon get the parts needed to make the epic stm t5.

Should i upgrade the weapons first or focus on the shield?. Also which weapons to prioritize over which?.

 

I should probably also mention that at this point I'm 25% done with getting my legendary lrm and 15% done with getting my legendary sniper.

 

You might want to consider tweaking that set-up a bit, as it lacks firepower IMO. Personally, I'd ditch the standard mortar and one of your LRM. If you want to keep the long range style, you can equip a rail gun. Missiles can be kinda rangy too and even though they aren't too good from a distance, they would make you much more potent at mid range. FBs can have good range with a couple of perks. Torpedoes can be sent off from across the map too.
But as it is, 2 LRMs and 2 snipers (plus an SM) leave you quite vulnerable when an unfriend gets a bit close. Those weapons' range comes at the price of lower damage. So if someone gets close (and it always happens during a game), you better hope for a string of criticals, otherwise anyone with XCannons, BC, grenade, carro, ML and other such weaps will eat you alive.

 

Got it thanks. I wanted to do the mortars first cause that's where most of my damage output comes from but you are right, my mortars don't lack dmg, my snipers kind of do and those are the ones I'll need if I'm stuck at close range.

 

Oh trust me, I've been playing this game for like ever since it went global and so I know, but you see I'm a free to play player and I didn't choose my setup, the setup chose me.
