I modified your teams slightly
Team 1: aka official team
Y'shtola (446 SPR)
Rikku (not sure what that would be - she has 5338 HP, 252 ATK and 263 DEF)
Fryevia (652 ATK, 544 MAG)
Tidus (533 ATK)
WoL (!!!!)
Team 2: aka off team for doing farmable content
Yshtola (similar stats to above with another esper)
Amelia (530 ATK)
Fryevia (same as above)
Wol
Tidus (516 ATK)
Also decide on a carry..
E.g. Fryevia
Most events are best farmed with bonus friend, full bonus party self save one spot, the carry, that should be able to mop up the floor..
Your most palatable candidate is fryevia, as tidus might not have enough mp to do a 5 stage clear on his own
What to give to whom..
La pots --> rikku
Stat pots --> Atkins to your attacker, hp/spr/def tank first, rikku second, then rest of the team..
Depending on the situation, you might not want to invest too many pots into yshtola... she's good, but a better healer should be in the pipeline at some point..
Also, tmr tmr tmr..
Your endgame is farming tmr..
Usually you do
1) core weapon for your dps
2) dual wield for all your dps
3) more dps gear
4) yet nor dps gear
5) realize that your tank dies too fast, and start farming some tmr go him
If you can run the game on android emulator, like memu or not, it's very easy.. if you can I can help you set it up in the beginning of august when I get back home..
Else I think there are some alternative on the phone itself, but I'm not too knowledgeable on the topic
Second topic:
Resource pooling..
Are you f2p? Giving the game money or will in the future?
Don't hesitate to ask for advice on pull and read defianthermit post on reddit ffbe..
For this banner.. welp..
An agrias might be nice, but you have her already..
A few gaffgarion for braced tmr would be nice, but not worth the risk..
5* units are luckluster..
Skip the banner, heck even dailies might be a waste..
