Need help for end game Lanka build

[Foxtrot39]

Cant find a way to make it end game ready

I've slapped multiple arcanes that would combined bump its damage by about 500% on both warframe and the sniper (Rage, arachne, implacable primary if that's the name)

I've put on the sniper aura and the mod giving me an extra 15% bonus from the aura

I have an S tier riven for it (120% multishot and 200% base damage for no drawback)

Yet still I am way slower than any random I find using a standard AR type weapon in term of TTK even swaping mod to test other elemental damage it just doesn't hit hard enough

unbuffed stats are

+7k/+22k for uncharged/charged shots

50/62.5% crit for uncharged/charged shot with 60% status and 5.6x crit multiplier chance on either

Weapons are not designed to be perfectly balanced and many of them are situational. Lanka is very situational because it isn't a dps weapon, it's a long range weapon that condenses lots of damage into a single shot, which in turn makes it decent in certain situations vs some bosses but bad for regular combat where you're fighting against hordes of enemies up close.

My advice is, don't use Lanka unless you're eidolon hunting or playing around with Mag's bubble. With Mag's bubble it's actually really damn fun.
