I'm bored at work and I have nothing better to do, sorry.
- Akh Morn will not be the Limit Break. Instead Bahamut will cast Akh Morn when summoned, dealing light AoE damage around the target. Ultima will be the Limit Break (like in FFVI);
- Bahamut and Phoenix will be the only Demi-Summons. They're too thematically important for FFXIV's story to put other ones at their level;
- You have an ability similar to Energy Drain/Siphon that only gives 1 Aetherflow and has a 30s cooldown. This alone will have three consequences: first, your burst will be way busier; second, you will have to fit two ogcds in the middle of a potential Ifrit phase; and third, you have to be careful not to overcap on Aetherflows when saving them on Phoenix phase;
- You have a new gauge, which increases by 5 whenever you spend a lego, and can be spent on a heavy-hitting ability at 100. You have 10 legos per minute, meaning that you can use this ability once every two minutes (as long as you don't die and use your summons correctly);
- Egi-Summons stay on the battlefield and attack their target just like Demi-Summons. At lower levels, the Carbuncle is the one who attacks. Also, Ifrit is the one who dashes and does the melee follow-up, not you. Radiant Aegis works all the time to make up for this change;
- Titan gcds have a 1.5s Cast Time. Enough of Summoners running around. You wanna use Fester? Radiant Aegis? Swiftcast? Use it beforehand or be punished;
- Ramuh, Shiva and Leviathan during Phoenix Phase. Their moves are completely different, and their legos are 3-3-2 instead of 4-4-2;
- No Mecha-Bahamut.
