If you decide to bring w/e job or kill speed doesn't matter, then go ahead bring w/e job you have. I'm merely correcting Omny's statement about stacking multiple GEO buffs yielding better result. My personal experience is that using COR+GEO tend to have significantly faster kill speed than GEO+GEO or GEO+ another DD. And I believe it's a useful info to know for those who actually care about the kill speed.
Also just FYI to those who think "it doesn't matter what job you use", yesterday I was in an ambu pt with 2 GEO, each fight takes 5.5~6.5 min without COR. As soon as I switch to COR we're getting 2 min win including 1 min buff time, we didn't change DD job nor member in the pt. IMO a 60%+ reduction in clear time by adding additional COR buff is not as irrelevant as you claim.
Alternatively you can have GEO entrust precision and have BLU cap haste themselves, or switch sam roll to hunters to cap hit rate and still get way more attack than GEO(fury/frailty)+GEO(precision/haste or DEX) setup. Even though GEO is consider the No.1 buff job, there's no need to pop on the forum and scream "GEO GEO GEOOOOOO let's invite more GEOs! More GEO the better" when GEO+COR often yield better result.
Also I've done pretty much every content that favors melee setup, I can't think of anything that I'd need 3 GEO in pt with 2 of them doing defensive bubbles atm. Most things I can think of uses 2 GEO max, with 1 GEO doing defensive bubbles and another one doing DD bubbles. Just because GEO is nice, doesn't mean you need invite THAT many GEOs and promote 3+ GEO setup.
