I hate the fact that so many champions from the old days have been left in the dust in terms of lore, most egregious examples being stuff like
and everything involving Bandle. Yes, they're slowly getting through these guys, the most recent example being
, but it's really painful to know that these champs still have barely more lore than what was there in 2009.
Also, when most champs finally get updated lore, we rarely get to go back to them. For example, the was for the Freljord was set up in a big way through a huge lore event like five years ago, and we haven't heard anything from that since, except building on it a bit with the Void being integrated. Lore progression is so rare that it's a huge deal when it happens (Confessions of a Broken Blade).
And when these lore progressions DO happen, we don't see the champs change in-game. Look at Nidalee, who just got a lore update, or Lissandra, who was reframed in the lore. Neither is reflected in-game. Nidalee's still a stripper and Lissandra is still a Captain Planet villain. I realize that budget constraints don't allow Riot to implement EVERY SINGLE LORE CHANGE in game, and if they wanted to VGU every champ they released lore for we'd never get any lore, but it'd still be nice.
TL;DR - So I guess the thing I hate most about the lore is that there's not enough of it, haha.
P.S. - I'd put
&
in that little list of egregious examples, but they're not far off from a proper full update, so they get a pass.
