To describe it shortly, the Pistol was never really broken. CE's sandbox was very limited because it was the
only weapon that was used midrange aside from the Sniper, so the fact that people call it broken is unfair in that respect.
Now compare it to the other weapons in their respective roles:
- PR/PP vs Pistol -> PR/PP had stun and would dominate the Pistol close range. If the Pistol won, then good job.. Doesn't mean the weapon is broken because there could be many factors that played into that (player skill, out of ammo, low health, etc.)
- AR vs Pistol -> AR had 60 shots and had an incredibly quick melee, and what made it more useful was that you could use it to activate Camo quicker by shooting a bullet.
- Shotgun vs Pistol -> Shotgun was an absolute monster. Nothing else to say about it.
- Sniper vs Pistol -> This is obvious.
- Rocket vs Pistol -> This is obvious.
- Needler was useless.
By giving weapons certain traits you increase their uniqueness and viability in the weapon sandbox.
Let me ask you, what's the most important factor in a video game?
Let me answer:
FUN.
So why are people shitting on a weapon that SOOOO many people found incredibly fun and rewarding to use? Also, I should throw out there (yet again) that not even professional Halo CE players can land consistent 3sk's on LAN, so obviously the weapon takes some skill to use.
Aside from weapons, another way to balance a returning CE Pistol would be to make a more responsive strafe, increase the movement speed and not have babby level aim assist like in Halo 2. Halo 5 can easily return to AR/Pistol starts granted the rest of the sandbox is balanced properly.
