Sion: Death Recap
It seems that Sion's death recap is strictly from the beginning of his passive proc to his (second) death, thus, preventing the summoner to accurately analyze how he/she was killed, leaving out valuable info to adjust their build strategically. I think most summoner's would agree that they'd prefer the death recap before the passive proc, as opposed to after; both would be ideal. I've only played Sion twice so far and already noticed this, so there is a good possibility this is already being worked on or at the very least talked about.
