I’ve made a post on this topic before the forum upgrade, when they first mentioned it. It’d be an opportunity to make leveling interesting again and I am all up for a level squish. For max level chars, it’d be the same as the (already two) ilvl squishes, the only difference it’d hit the “level” number.
Also, if they really wanted, it’d be a chance to bring back something on (almost) every level, if they gave many abilities sooner but in weaker versions - they’d be “powered up” later through ranks which would prevent the hard-hitters to be too strong at lower levels. They could also do it the same with abilities having charges (starting at one, getting more later) and passives (what’s now 25% chance right away could be split into 5%, 15%, and 25% ranks over the leveling).
The way I’d see it, levels of:
Spec at 5, talents: 10,20,30,40,50,60
Mounts: 10,20,30,35,40. Personally, I’d make a change to flying structure from 150%/280%/310% to something like 170%/240%/310% and nerf the cost for the mid tier but that’s just me. Ghost wolf/travel form at 7.
Allied races: 10. DK: 28. DH: 38.
LFD: 10, Glyphs: ability-dependent but not below L10
Zones:
Start 1-5
Vanilla 1-30 (similar to today’s scaling, just divide the entry level in half)
TBC-LK bracket 28-40 (Hellfire, Zangarmarsh, Borean, Howling fjord 28+, the rest 30+)
Cata, MoP 35-45 (Jade forest, Hyjal, Vashj’ir 35+, the rest 37+)
WoD 40-50, Legion 45-55
BfA 55-60 (Changes to 50-60 on 9.0)
Next expansion 60-65 (changes to 55-65 on 10.0) etc.
The point is to have overlaps to always be able to skip a continent if you want to stay in one.
