Need a little newbie help here

I think that quote assumes that I win, correct? I do not think that you get Squad Arena Tokens if you lose (but Please correct me if I am wrong, like I fervently Hope that I am), and Lately, I win one battle out of the (what is it, five) that get allotted before Squad Arena cooldown period. And that is if I am Extremely Lucky...

It doesn't matter if you win any particular battle, it only matters what your rank is at exactly 6pm. If you click on the prizes tab in arena it shows you the rewards for the different rank tiers. If you are rank 140 at payout time, you get the rewards shown for the #101-200 tier, which is 600 arena tokens, 75 crystals, and 20k credits. These rewards are delivered to your mailbox at 6pm.

Galactic War is also suffering, by the way. I used to always win at least Ten battles before my “A” team gave up the ghost.

Not sure if you know this or are doing this, but one good strategy is, if you have multiple characters that may be helpful for you in GW, use them in the very first couple of easiest nodes, even if they aren't part of your "A" team that you'll use for most nodes. That way they get turn meter and if you add them in later on they are more likely to go before the opposing team.

P.S. just before I posted this (I write everything in a Word document first now, in order to cut down on “Edits”), I lost All of my Arena Fights; I did not even have a Chance. Here is the latest lineup that butchered me; Hera, Chopper, Ezra Bridger, Zebediah “Zeb” Orrelios, Kanaan Jarrus. Chopper kept “taunting” to pull attacks away from the others, and when I Did finally kill him....He revived!

Hera has an ability to give other members of the team the "backup plan" buff which will cause that character to revive if you kill him while he has that buff on. It's important to know what the various buffs and debuffs you are facing do because it can impact the choices you make - you can click on them in the battle to get a description.
