League needs a "Try Champion Mode"
Something that you can start on the store page or champion info page to try out that champion in an ARAM style map (something small with an enemy bot and ally bot in case you're trying out a support) and the modifiers that are in the Practice Tool, so that we can try out a champion before buying them to make sure we really want to spend our Blue Essence on them (given how we only have 3 refunds and they don't recharge, and how a large portion of the roster is 6300, and BE gain isn't that splendid last I checked).
Until we get daily missions that give us BE at a better rate, we need something to make sure our currency isn't wasted.
That or unlock all champions in Practice Tool.
Thoughts?
