Is there even a point in leveling up Honor level anymore?

New question: Is there a list of what bonuses are available for which tier?

Wondering what the best bonuses I can get without Legendary are. I read somewhere that you need Legendary for the Attack Speed one, but don't know what I should try to aim for without Legendary.

Rare: Nothing, move on
Epic: 19% buff duration or 6 w.att, rest is crap
Unque: 32% buff duration, 15% crit rate, 5% boss dmg, 15 w.att rest is crap.

Edit: You can also get 8% drop rate on epic and 13% on unique, but rarely anyone want to stick to that.
