I really hope they don't just raise the level cap to 110...

I expect they'll just halve everything, since we're at level 100 now. So rather than the current level brackets, we'd have:

ARR: 1-25
HW: 25-30
SB: 30-35
SHB: 35-40
EW: 40-45
DT: 45-50
New expansion: 50-55, or 50-60, probably better to do the 50-55 for futureproofing

ARR has too many dungeons compared to other expansions. Additionally, there absolutely has to be that first 10 levels where it is so easy to gain EXP that you can just kill enemies.

Jobs get unlocked at level 30, and HW jobs start at level 30. This also is when you can PvP. This all would make it logical for ARR to end at level 30 in a rework.

While expansions could just increase by 5 levels, the progression already feels slow due to being spread over only 10 levels instead of 50. So we could go 35, 40, 45, 50, 55, 60, but we could also go 30, 40, 50, 60, 70, 80 and then 90 for 8.0.

However, if they plan to continue level increases beyond 8.0 and want to keep it under level 100, they'd have little choice but to increase by 5 each expansion.
