Currently, the only way to search statistics (player statistics) is to repeatedly search for summoners by name via the summoned search (as far as I can tell). Not sure how much the server would appreciate so many requests coming from one client, however.
I'd be more interested in exposing the following data for purposes of theorycrafting apps:
-Base stats, stats per level
-Abilities and ability stats per level (inc bonus % from AP/AD/etc)
-items, item data
Other nice to haves:
-rss feeds for individual summoner match history, ladder info, news, etc
Honestly, any kind of service that is easy to consume that exposes lots of raw data (let the community figure out how to use it) would be great.
I imagine this is a low priority, as its difficult to quantify monetary worth vs the cost of resources it would take to implement, but it would be nice to hear if it was even on the table.
Or any chance we get a lolarmory.com any time soon?
