For those that are not familiar with it, a BeeFour is a build that aims to take advantage of the Bee, relying on Willing, Pressure and Drawing aggro with the turrets to keep it up as much as possible, and on fire rate skills like Metal storm to get the most out of it.
As there are no clear cut best COM for a setup like that, I decided to compare their pros and cons to come up with an answer, and while I was there, share my thought process with you guys (as it may help others in making the same kind of choices) and maybe get some valuable info in the form of feedback. 
Here’s the build I came up with in an earlier discussion on the subject.
http://bl2skills.com/commando.html#55055150015005010000005054105151
There are 2 unspent points and obviously I can move some points around to take advantage of COM bonuses.
Some skills are negotiable (like impact and forebearance) but I will not change my build completely, as I feel this is pretty close to an optimum setup.
(I also will not get into the “Quick charge is good with the Bee” debate, as I feel everything pertinent has been said already, @johnrr6 agrees with me, so it’s good enough for me)
To complete the picture, gear-wise, the best suited gun types for that kind of build are SMGs and ARs (especially the later), since they have a high fire rate and decent-to-great accuracy. Pistols are pretty good too in certain cases (Hyperion, Vladof)
Other pistols, Snipers, and rocket launchers are too slow, and shotguns divide their amp bonus among all their pellets, and once that is done, they are still too slow
So, mostly ARs and maybe SMGs and Pistols, so keep that in mind
I intend to use either transfusion or singularity grenades. the first one heals and the second one buys time to recharge my shield and reposition.
As for relic, I will complete the build with one that addresses whatever important metric hasn’t been addressed by my COM, but here’s a short list of the possible choices:
- Bones of the ancient
- Blood of the ancient with ammo for what I use (and the extra health of course)
- Skin of the ancient (especially one that have a shield recharge delay bonus)
- Allegiance relic for whatever manufacturer I end up using
- Shadow of the seraph (moar bullets!)
- Sheriff’s badge, if I end up using a pistol
On to the analysis then!
When deciding on a COM, My priorities are (in that order):
- Keeping my Bee up (so, shield skills and things that make boost my turret health/cooldown to draw aggro)
- Increasing Bee delivery (so fire rate first, then reload time, accuracy, mag size… anything that means more lead per seconds)
- Stay alive (since i’ll be functionally playing without a shield, I need to be able to stay alive if I get in a pinch. That usually means health, health regen, but also things like Grit and FFYL skills) I may also address that issue by using Moxxi guns if the need be (though with fire rate and accuracy being important points, I would be severely limited in choice.)
What I don’t care about is Gun damage/grenade damage: with the Bee, any increase in gun damage is insignificant, and grenade damage suffers the same thing.
What skills helps with the first point: Willing and Pressure, but also Forebearance (as a DoT that ends sooner, means a shield that starts charging sooner too) and Onslaught (as it helps positioning)
and also all the turret skills.
With the second point: Metal storm, And to a lesser degree Ready and pressure. I also have the option to spec into overload if I do go with ARs.
And with the third point I have Able, Preparation, Grit, as well as anything that helps with my shield of course. I also leave the door open to Healthy, Quick charge and Last ditch effort
So of course, any COM that boosts these will be considered, as well as those that have base bonus in line with the effects desired
I’ve narrowed my selection to 6 COMs that I feel bring something to the table:
##Gunner
The Gunner COM boosts Fire rate, Metal storm (more fire rate) and Overload. It seriously addresses point #2 but fails to address the 2 others. Still a solid contender
##Tactician
A boost to shield recharge delay/rate is very good (better than 5 extra points into Pressure). Add to that a bonus to preparation and resourceful, and you have a COM that checks point #1 and #3 admirably.
##Ranger
With a Chaotic Evil version, you get extra fire rate and extra crit bonus, both of which translates to a big boost to point #2, you also get a bonus to Grit for point #3.
##Legendary Pointman:
This one does more for point #3 than almost all the others combined. Max health, health regen, bonuses to Grit, healthy and Able, you almost have to want to die with this one. But it does very little for my 2 most important points (Only Pressure for #1 and …nothing at all for #2 )
##Legendary Ranger
It addresses #1 with its base bonus and #2 with Metal storm, but does very little for point #3
Still, the 2 things it does well are solidly in line with my 2 most important points, so it’s worth considering.
##Legendary soldier
It addresses all 3 points (Cooldown for #1, Ready and fire rate bonus for #2 and Preparation and healthy for #3.) …But it does so very mildly, as most of these bonuses are little help at best, especially when compared to a boost to shield recharge like the Tactician or to Grit or metal storm.
I want to hear what you guys think.
I have never had as big a dilemma in choosing a COM before, as usually, a clear choice emerged.
Let’s discuss this shall we ?
