I don't get a single new ability from level 80 to 120

The leveling system is in a dire need of a rework. There is nothing to look forward to each level, other than it all being over once you hit max and can "finally play the game." How would you change it?An idea I suggest is taking an idea from Legion. Remove the level requirements of abilities, instead give players points that they spend in a diverging tree that can be customized in different ways as your level. It being all filled up when hitting max level, similar to artifact weapons.I would also love to see class trainers introduced in the way the monk's peak of serenity is used. A daily that gives an hour bonus after training, quests that give minor tips and advice with large xp rewards. This could be a way to reuse class hallsI would also like to see some old content relived. Maybe a LFR for level 50s to 60s for molten core/neltharians lair that give a bunch of xp, with BC and WotLK raids on the 60 to 80 bracket. Adding more ways to break up the monotony of quests and re-use content that is already in the game, with the added benefit for new players to experience raids like Ulduar and ICC in the way it was meant to be experienced (not just one-shotting everything as a max level).What do you guys think?
