I am trying both of these with my fc which have some exceptional players (but not enough to make 8 ppl party) but mostly casual players that play on free time for fun or play their first MMORPG. Haven't tried much Titan ex and Turn 5 because it doesn't seem worth to keep wiping at exactly same point all time but I think we will clear both right after 2.3 because with new gear (and possibly more echo) it will be possible to beat those fights even if couple of members panic during the fight.
So far our fc group usually can't kill Titan adds and Asceplius fast enough
