I expected this to happen, so I am keeping records of my Honour points in an Excel document.
~1155 Honours total, including from premades, so far this season. There is the occational delay on receiving them, so I might have left the lobby too soon sometimes to get them all recorded.
I am marking out every checkpoint to get an estimate of games and honours needed between them. I am also noting the number of "Everyone on your team honored a teammate! You got a little extra Honor progress this game.", and what sort of Honour I get (Friendly / Calm / Leadership) and who "was the most honorable player on your team".
Received my second Honour level 5 orb a few days ago (which is basically Honour level 5, checkpoint 2), and am currently about 1/5 on my way to the next one.
But seriously, the Honour system is overrated - the rewards feels...acceptable (no more, no less), but nothing to celebrate. Some BE and some Hextech keys, and that's about it.
