That said I want to put something in perspective:
Number of buckshot PB shots until xeno is KO
[Y = Young, M = Mature, E = Elder, A = Ancient]
1 hit KO
- larva
- drone
- runner
- sentinel
- lurker (Y-M)
- burrower (Y-M-E)
- spitter (Y-M-E)
2 hit KO
- lurker (E-A)
- burrower (A)
- defender (? maybe 2-3 ?)
- spitter (A)
- carrier (???)
- hivelords (???)
- boilers (???)
3-5 hits KO
5-8 hits KO
Number of slashes until marine is KO
~5 slashes KO
~10 slashes KO
~15 slashes KO
- burrower
- spitter
- crusher
- runner
- carrier
- hivelord
- defender
~20 slashes KO
Seems pretty fair eh? All T1 unga dungas get a death weapon that is arguably more deadly than some specialist weapons. I've seen queens and ravagers take +7 slashes to kill off a single marine. THERE IS NO XENO CASTE THAT EXIST THAT CAN INSTAKILL MARINES IN 1-2 HITS. PERIOD. (nor should there realistically be) Also since this game is 80% marine players, I'm not surprised that most of the conversation is overwhelming negative in regards to xeno complaints.
The bottom line is this: Shotguns
needs a weakness. Since xenos are melee oriented, they can't fight effectively with ranged attacks other than a few side castes that do laughable damage output or easilyy avoidable attacks. The way it is now, marine are more deadly in CQC with buckshot shotguns than xenos.
That's a fact. What is the solution? Here are some realistic options:
Nerf ammo capacity (make extended ammo capacity an attachment)
Nerf shotgun damage output (but give BCs a big damage boost to restore to the same output)
Nerf pumping time (add an attacthment to decrease this)
Nerf AoE or stun (maybe more attacthments or BC that adds this capacity)
Personally I'd experiment with lowering the ammo capacity first. See the effects. Marines shouldn't be able to spray and pray shotgun buckshots like it's a SMG. If it still seems overpowered, I'd drop the damage quite a bit and let a BC boost the damage output to the same level it currently has.
Also something has to be done about one handed firing and pumping. You should only be allowed to pump with two hands.
