No, not worth keeping at all. What do you miss to keep soulcry, Refreshing Sonata?
++Soulcry adds a fixed 450 p.atk after buffs so it'd be like a 10% boost, which is nothing when you can have faster skill re-use and les MP consumption for your skills and a buff so parties won't complain that you lack it when you group with them.
Personally I'd keep neither soulcry or soulguard since both are replaced by better skills that parties will ask for.
ISS is a party assisting buffer/debuffer/dd not a selfish toon for weak self toggles.
i kept soul cry for a very short time.
i thought that it was replaced by something that didn't work with Harmonies.
Prevailing Sonata increases max hp, attack speed, cast speed, and other good qualities. even in Oly, you'd be missing the buff.
it's nice to have that extra p.attack, and if you know you will always have a second enchanter, you can keep it.
but you will need it if you are a sole enchanter for a group.
because Prevailing Sonata is better.
soul guard, which is nice to keep, does give up knights harmony.
sadly it's a hard decision.
because knights harmony and soul guard stack.
so you could have a huge p.def advantage at the cost of some mp drain.
however, people will complain a lot if you can't provide knights harmony.
and probably even more if they feel their hp is low due to lack of prevailing Sonata.
Alright, had my first group at SoA today and kicked Soulcry. That HP buff alone is worth it.
Our real strength is probably that pdef and patck debuff on the mobs, much more important than our damage.
