As an added tip, you typically want to always be in, around, or near cover for when you do miss. In the event that you do miss, run like hell.
And to clarify the interchangeable part:
a) If you do wind up getting a lucky (or skilled) pig shot, hitting him her zed with a primary should be relatively easy because it would only require one shot. Spray em down with the CCG.
Typically, when you use LTL, opps tend to be a more aggressive. This comes from the ignorance of the power of 1-shot + pig. You can expect them to push you a lot and get in range of your pig a majority of the time. Once they learn, they'll play a little passively.
Rule of thumb for those criminals: if you see someone running LTL, Don't. Get. Close. And always assume the guy has a pig.
b) If you hit them enough times with your primary, you can start to move in for the pig shot. It's very important to anticipate the opponent's movement...as well as other opponent's movements.
LTL'ing a solo player is relatively easy because focusing on him is easy. When it comes to multiple people, you tend to find yourself rushed by both of them. Deaths with LTL (in my experience) usually occur when a second opp comes in.
As far as continuously hitting them with the primary, it goes like this:
Each shot refreshes the "final blow", and the final blow wears off as the opp regenerates stamina. Theoretically speaking, the pig would do 90 stamina damage. Since the stabba ccg deals 12.5 stamina damage each hit, you're given 2.5 points of stamina window to hit them with a pig.
It takes 8 shots with a CCG to stun.
It takes 3 shots with a NL9 to stun.
It takes 2 shots with a pig to stun.
It takes 1 shot CCG and 1 shot pig to stun.
It takes 1 shot NL9 and 1 shot pig to stun.
Remember, you don't always have to stun them with the pig. Do so when the opportunity presents itself.
Please note that I'm not a total expert; I've just now started playing like this.
Anything that might need addressing?
