250 summon shouldn't be going anywhere, should remain a permanent feature. That said, it's still a 250 Lapis shot at Zidane in all his 1~2% glory. I've been pulling and I'm not unhappy with the results, Lani, Panelo, Russel, Xiao, and Vivi so far. For 1250 Lapis, I don't mind those pulls one bit. But it could've just as easily been 5x Lani/Vivi. Or there coulda been any other unit in as well, WoL, Chizuru, Zidane, etc. I'm sure you know that, it's just 50% off a pull can really pay off in the long run. Biggest problem is it's not really viable long term, you'll eventually need to purchase Lapis to keep up the daily pull unless you've been diligent with trophies and hoarding Lapis.
We're getting the next island this Friday so that'll help. It'll also be a good bit bigger than the third island with three cities and six exploration areas. As others said, grind grind grind though. Colosseum, Hero Ring mats, Awakening mats (3x Int Awakening Vortex per day at least for daily), rank grinding, leveling up other units for options, Esper levels, TM grinding, etc.
Grinding Expedition into the Abyss is a waste IMO. It's not so much that the 15% HP is bad, it's that the opportunity cost is too high. You're blowing 15 energy for 180 rank exp (compared to 500 rank exp from 2* esper fights for 15 energy) so that after 10-20ish runs, you can get an extra 5% HP compared to an easily grinded FP TM, nevermind the massive cost in Megacysts and such. The other two abilities are largely trash as well. I'd rather grind TMs, rank, or Hero Ring mats.
