Right now, studio fights are very difficult to review. The options to "Start from the beginning", "Start from your character", "Skip completely" are rudimentary at best. The replay is also only at one speed.
I think this causes two problems:
1) If a studio boss or producer wants to review a fight, it is really painful. Often you want to check the equipment a particular player is wearing. Or how many crits your opponents scored. Or why opponent X defeated five of your studio mates. Or to gather any other information about why you lost that fight you expected to win easily. But you have to plow through everyone, in order, and if you miss some information about a player, your only option is to basically restart. Gets very tiresome the fourth time through a fight trying to get to a particular part.
2) In anecdotal information, even casual players simply skip the replays. At best, they skip to their own toon, watch their own fight, then skip to the end. This means many heroic performances are simply missed, by everyone. I've had players say in chat, "I defeated five players that fight!" but just did want to wade through the rest of the fight to see their heroics...
My suggestion: I can live with one speed of replay, if I can skip to a particular player from either studio.
My suggestion is that list of players for each studio should be live. Clicking on a player's name, from either studio, will take you to the first action taken by that player. The rest of the interface need not change.
The function to jump to a particular player's actions seems to already exist, so this should hopefully be relatively easy to implement. (Easy for me to say, not having access to the code. )
