It's kind of fitting as he's been using unlikely team to beat hard enemies only yo lose to an unlikely tough enemy team.
To me, Lloyd infernal map is the easiest because of the extra unit that was easier to kill initially than the lunatic map.
Yeah, that's what I said previously. Lloyd is what many, including me, consider to be the easiest among infernal GHBs so at first it felt hard to believe. However, our teams are very different from a team of 4 Sakuras. We might not be able to see the contributing factors to the difficulty unless we think in the Sakura guy's perspective.
In terms of map and terrain, there is no defensive tiles in the Lloyd GHB map. This is something the Sakura Squadron often need to rely on in the past infernal GHBs. Also, the map is more open than most of the previous GHBs, providing fewer possible choke-points for the Sakura Squadron to utilize.
In terms of enemy composition, out of all the six enemies, only one of them is a mage, which I think is the lowest number among the infernal GHBs. All the physical attacker has around 50 atk. The Axe Pegasus and Llyod even have high speed and res. These could be very difficult for Sakuras to handle.
