hmmm considering the information from you, i will not recommend hercules talissa to LB-ed, & ur talissa kratos a bit sad actually, u should make ur hercules talisa instead of the kratos one(i assume u got the kratos talissa first before the hercules one), so.. back to topic, i don't know what's ur current arena ranking so i assume it's below 3600,
IMHO i will not recommend to make ele talissa,
So my recommendation base on ur list:
-Faye HD
-Talissa warlock
-Ronan Rune magus or Mind warder(ur choices depends on what kind of squad u think hard to faced ), but my recomendation will be rune magus, because the aura(can strengthen uur talissa)
-Leon BK
-Theia Archbishop
The last 2 just to complete ur squad
