I'm especially curious as to how the Leviathan & Ramuh Egis for SMN will be affected by the level cap increase. Will you have to have completed the Level 50 content to get them, just like the first three? Or will you be able to do it at Level 55/60 regardless as technically the player "canonically" has defeated all the Primals?

Personally I think that having to do three Level 50 storylines just to get those two pets, and by extension queue for dungeons that hardly anybody goes to anymore, would be a HUGE turn-off for new SMNs who level the class after Heavensward goes live. The DPS queues for all the dungeons you need in Main Scenario are bad enough as it is.
