Which are the most important skills for a Ranger & Gunner?

[MasterGunz2345]

I plan on only using these classes, so I need to know which skills from the skill tree are the most important to upgrade to. Or, which skills do you recommend to upgrade so that my Ranger/Gunner can become and excellent character? Thanks

So you'll always be playing GU/RA or RA/GU then?

Then this is your skill tree. http://pso2-skill.pwnedgalaxy.net/sk...00000Ib000000j

Ranger Must Haves:
Weak Bullet (Lv1, 3, 6, or 10) [Each of those levels gives an additional bullet to use. IMO, Max this]
Weak Hit Advance 1 (Max this)
Weak Hit Advance 2 (Max this)
+ Prereqs.

Ranger Situational:
Standing Snipe 1
Standing Snipe 2 (If you use Gunner often, you'll be flipping before every attack, this won't trigger that often)
Sharp Shooter (If you use Gunner often, you either get this, or Zero Range Advance bonus damage; and ZRA is a higher modifier.)

Ranger Helpful:
Just Reversal (If you don't have it on your main/sub combo)
Rare Mastery Ranger (Lv1 only; if you are Main-class Ranger and have a 10* weapon)

---------

Gunner Must Haves:
Twin Machine Gun Gear (Max this)
S Roll JA Bonus (Max this!!!!)
Zero Range Advance 1 (Max this)
Zero Range Advance 2 (Max this)
Perfect Keeper 1 (Just because it's 1 point after already having ZRA2 Maxed)
Chain Trigger 1 (Just because it gives you the ability to use it, and it's just one point)

From there, you would either push towards;
- Chain Finish if you like Chain Trigger
- Attack PP Restorate if you want to recover more PP so you have less downtime from spamming PAs
- Perfect Keeper, if you value dps. But you either need to not get hit, or own a Guld Milia to keep you at full HP.

Gunner Helpful:
Just Reversal (If you don't have it on your main/sub combo)
Rare Mastery Gunner (Lv1 only; if you are Main-class Gunner and have a 10* weapon)

=============

But unless you really wanted to switch between Launcher and Twin Machine Gun at a moment's notice, it might be beneficial to also level up Hunter.
Hunter subbed to either of those will give you more gain then having GU/RA sub each other.

So with either RA/HU, or GU/HU, you want...
- JA Bonus 1 (Max)
- JA Bonus 2 (Max)
- Fury Stance (Max)
- Fury S Up 1 (Max)
- Fury S Up 2 (Max)
- Fury Combo Bonus (Max)
(Recommended Optional) Just Reversal (which means you also have Step Attack)

The added bonus is that you don't have to waste RA/GU points on Just Reversal.

You don't have to use Hunter weapons or anything since you probably want a gunslinger play style. You just use Hunter Sub for its Fury Stance modifier to increase your damage by +93%

Here's an skill tree to get you started with those 3 classes skills partially filled out.
