Just to add, I find the raid events to be extremely time(and seed) consuming to MLB both eidolon and wep unless you nail the gacha at least once. The divine/devil souls arent too bad but maxing the PP rewards is ridiculous.
Same for the union event we just had. I ended up with about 8mill individual PP but we only had about 4-5 players in my union actually contributing much... So yeah, I ended up one short on both the weapon(which is pretty damn good), and the eidolon(which is total garbage, except -maybe- the active effect)
