Since SE are revamping old content there is a bit of old cotent that i feel could be revamped for fun and some nice endgame.
Memory BCs
These are reworked Mission battle fields where the enemy have been strengthened to give a challenge to 6 99 players.
For exmaple.
Rank mission : Dragon and Eye BC, Shadowlord BC
Zilart : Ark Angels !!!
CoP : Tenzen, Promethia and provy fights!
ToAU : Alexander, Gessho
WoTG : Cith sith, Atmos and the final boss (alot havn't got there yet)
Either way there is ALOT of content there they could revamp as for rewards 3 things come to mind.
1. Conquest points + Imperial standing + Allied notes
2. Items to upgrade some CP,AN,IS items
3. A method to reobtain and upgrade some mission rewards like Raja Ring to 7 STR 7 DEX and 7 STP and 7 Sb.
The reason i want this is that it's kinda sad we lost some of these amazingly designed fights when the caps were removed and i understand why it was done.So it would be great to bring them back as endgame content since some of these fight are fun and invole real strat. ^^
Also a new way to obtain CP, AN and IS would be nice (AN are easy to obtain atm anyway).
