Any Armageddon CORs/RNGs willing to share their experience with it? Have about 50% of the HMP on a mule and considering making one.
For cor: Best wildfire gun, sidegrade shooting gun with last stand.
Best macc and racc bullet.
It has the potential to beat Fomalhaut for shooting but several condition must be fulfilled:
1) you need bullet from Fomalhaut
2) you have appropriate AM up/down tp set. Sets are posted in the guide.
3) You have triple shot up as often as possible to get the most out of AM3 white dmg and minimize AM3 upkeep time. You certainly don't want to shoot your way to 3000 tp without TS.
With TS up though, extra hits from triple shot/quad shot really really benefits AM3.
4) NM takes minimal SC damage.
5) ideally it also has some sort of Amnesia move.
Note that while Fomalhaut may seem interior to Arma on parse when 1-3 conditions are fulfilled, the sc damage from Fomalhaut often pushes it equal or ahead of Arma since it's easily 1/5 of its total dmg or more. Arma is only really really awesome when at least 1-4 of above conditions are met.
Fomalhaut also has the advantage of being fool proof and easy to manage, Armageddon needs more management and skill to get the most out of it.
It has best racc and macc bullet though, I use the racc bullet quite a bit, and it's nice in situations that I'm getting melee buff but need to switch to ranged mode. In that case I'd need quite a bit of racc.
Tl;Dr: Get it if you are a hardcore cor and aim to have every tools available to perform at max potential. If not for the situations that you need it at least for the bullet. But it's the lowest priority out of cor big 4 gun. TP bonus, Fomalhaut, DP absolutely should be higher priority.
